The Honorable Board of SupervisorsJuly 8, 2008Page 2
3. Authorize the Acting Director of Public Works to use a Board-approved JobOrder Contract for the Alondra Park Pool/Water Play/Skate Park demolition,site clearing, and rough grading.
PURPOSE/JUSTIFICATION OF RECOMMENDED ACTION
The purpose of the recommended actions is to comply with the California EnvironmentalQuality Act (CEQA) by adopting the Final Mitigated Negative Declaration and MitigationMonitoring and Reporting Plan (Attachment B).
The recommended actions wil also allow the Department of Public Works (PublicWorks) to proceed with the demoliion of the existing pool, bathhouse, restrooms, andequipment buildings. This will provide an area for the acceptance of fill material as itbecomes available, thereby reducing the costs associated with the fill operation andeliminating any unknown construction issues prior to bidding on the project.
Alondra Park is a community regional park of approximately 84 acres and a serviceradius of 20 miles located at 3580 West Manhattan Beach Boulevard, Lawndale,
California. The project site is in the southern portion of the park on Redondo BeachBoulevard adjacent to EI Camino College. The existing pool, bathhouse, and equipmentbuilding (constructed in 1960) have exceeded their useful life, contain hazardousmaterials, and are not energy efficient. The proposed project, in two phases, entailsdemolishing and replacing the existing facilities with a new 25-yard by 25-meter pool, a6,000 square-foot pool house and recreation building, a 3,000 square-foot water playarea, a 14,000 square-foot skateboard park, a new restroom building, picnic shelter,and various general improvements.
The project will incorporate energy and water conservation efficiency devices, lowimpact designs, drought tolerant landscaping, and other sustainable green buildingfeatures that will meet certification requirements of the United States Green BuildingCouncil's Leadership Energy and Environmental Design program.
Following completion of construction documents and jurisdictional approvals, we plan toreturn to your Board to adopt plans and specifications and advertise for bids to constructthe project.
Approving the recommended actions will allow Public Works to move forward with thedemolition portion of the project. We plan to perform this work using a Job OrderContract previously approved by your Board.
The Honorable Board of SupervisorsJuly 8, 2008Page 3
Implementation of Strateaic Plan Goals
The Countywide Strategic Plan directs that we provide Fiscal Responsibility (Goal 4) byinvesting in public infrastructure and improving the qualiy of life in the County. Theproject also addresses Community Services (Goal 6) by improving the quality of lifethrough park improvements. There will be no impact to the County General Fund.
FISCAL IMPACT/FINANCING
The total cost of the project, including plans and specifications, plan check,
construction, equipment, consultant services, Civic Art allocations, and County services,is $19,130,318. Sufficient funds are available in the Fiscal Year 2008-09 CapitalProjects Budget under Capital Project No. 86749. The project is funded by $14,639,318in net County cost and $4,491,000 in funds allocated for Enhanced Unincorporated
Area Services. The Project Schedule and Budget Summary are included in theAttachment A.
Operatina Budaet Impact
Following completion of the project in Fiscal Year 2009-10, the Department of Parksand Recreation (Parks and Recreation) anticipates one-time, start-up and ongoing coststo operate the new pool, pool building, water skate park, and skateboard area. Parksand Recreation will work with us to determine the appropriate level of funding when theproject nears completion. Request of funds for one-time and ongoing costs wil beincluded in the Parks and Recreation's Fiscal Year 2010-11 New Facilities request.
FACTS AND PROVISIONS/LEGAL REQUIREMENTS
Not applicable.
ENVIRONMENTAL DOCUMENTATION
An Initial Study (iS) was prepared for this project in compliance with CEQA. The initialstudy identified potentially significant environmental effects of the project, but prior tothe release of the proposed Mitigated Negative Declaration (MND) and initial study forpublic review, revisions in the project were made or agreed that would avoid the effectsor mitigate the effects to a point where clearly no significant effects would occur. Theinitial study and project revisions showed that there is no substantial evidence, in light ofthe whole record before the County, that the project, as revised, may have a significanteffect on the environment. Based on the initial study and project revisions, an MND wasprepared for this project.
The Honorable Board of SupervisorsJuly 8, 2008Page 4
Under CEQA, any lead agency preparing an MND must provide a public notice within areasonable period of time prior to certification of the MND. To comply with thisrequirement, a public notice was posted at the site for a 30-day public review period,which ended November 2,2007 (State Clearinghouse No. 2007101014). Copies of theMND were also provided to the Los Angeles County Public Library, City of TorranceLibrary, City of Redondo Beach Library, and the Lawndale Library for public review.The comments received on the draft MND did not require a response, but were includedwithin the final MND. A Mitigation Monitoring and Reporting Plan was prepared and willbe implemented prior to and during construction.
The California Global Warming Solutions Act of 2006 (AB 32) addresses the reductionof greenhouse gas emissions. As a result of this Act, an addendum was prepared to theAlondra MND to show compliance with AB 32.
The proposed project's impacts to greenhouse gas emissions from construction andoperations are considered less than significant. The conclusions in this IS/MNDaddendum are consistent with the conclusions provided in the previously circulatedIS/MND and provides a factual basis that the proposed project will not have a significanteffect on the environment with the implementation of additional mitigation measures.
The previously circulated IS/MND and associated addendum presents the appropriatelevel of analysis in accordance with CEQA Section 15063(c)(5).
The location of the documents and other materials constituting the record of theproceedings upon which your Board's decision is based in this matter is Public Works,Project Management Division II, 900 South Fremont Avenue, 5th Floor, Alhambra,California 91803. The custodian of such documents and materials is Mr. JamesKearns.
The project is not exempt from payment of a fee to the California Department of Fishand Game pursuant to Section 711.4 of the Fish and Game Code to defray the costs offish and wildlife protection and management incurred by the California Department ofFish and Game. Upon your Board's adoption of the MND, Public Works will file a Noticeof Determination in accordance with Section 21152(a) of the California PublicResources Code and pay the required filing and processing fees with theRegistrar-Recorder/County Clerk in the amount of $1 ,850.
IMPACT ON CURRENT SERVICES (OR PROJECTS)
There will be no negative impact on current County services or projects during theperformance of the recommended services.

The Los Angeles County Department of Public Works (LACDPW) (applicant) is proposing toupgrade the facilities located within Alondra Community Regional Park, also referred to as"Alondra Park" or "proposed project". The improvements are required to upgrade facilities inneed of repair. The Alondra Community Regional Park encompasses approximately 84 acres ofland and includes a children's play area, an urban lake, gymnasium, lighted baseba11softball
fields, multipurpose room with kitchen, picnic areas with barbeque braziers, a swimming pool
(currently unused), and a volleyball court. The improvement would be located to the north of theexisting parking lot on approximately 1.5 acres and would include redevelopment of the existingswimming pool and picnic area and construction of a new pool house, water play area,recreational office, and skateboard park.1-
f . During the initial California Environmental Quality Act (CEQA) review process, it wasdetermined that potential impacts would be less than significant with the implementation ofmitigation measures. As a result, this Initial Study/Mitigated Negative Declaration (IS/MND) wasconsidered the appropriate documentation for the proposed project. The IS/MND was submittedto the State Clearinghouse (No. 2007101014) on October 2,2007. This addendum to the IS/MNDresults from policy and regulations pertaining to greenhouse emissions, such as the CaliforniaGlobal Warming Solutions Act of 2006 (Assembly Bill No. 32; California Health and SafetyCode Division 25.5, Sections 38500, et seq., or AB 32).

CHAPTER 2Initial Study Addendum
2.1 Environmental Setting
r- :
The proposed project site is located within the South Coast Air Basin (SCAB), an approximately6,745-square-mile area bounded by the Pacific Ocean to the west and the San Gabriel, San
Bernardino, and San Jacinto Mountains to the north and east. The SCAB includes all of OrangeCounty and the non-desert portions of Los Angeles, Riverside, and San Bernardino counties, inaddition to the San Gorgonio Pass area in Riverside County. The Basin is a coastal plain withconnecting broad valleys and low hills, and its terrain and geographical location determine itsdistinctive climate. The general region lies in the semi-permanent high-pressure zone of theeastern Pacific, resulting in a mild Mediterranean climate tempered by cool sea breezes with lightaverage wind speeds. The usually mild pattern of the climate is interrupted occasionally byperiods of extremely hot weather, winter storms, or Santa Ana winds.
l .
l.
Sources of air emissions can be categorized as either stationary or mobile sources. Stationarysources occur at an identified location and are usually associated with manufacturing and
industry. The Alondra Community Regional contains recreational land uses, and the primarysource of air pollutants resulting from such land uses is mobile sources (e.g., motor vehicles andtrucks that traverse the local roadway network). Additional emission sources from recreationalland uses are typically maintenance related (e.g. landscaping and lawn care equipment andpainting activities) as well as indirect emissions result from electricity generation to provideelectricity to the site operation.

L
The accumulation of greenhouse gas emissions has contributed to an increase in the temperatureof the earth's atmosphere and contributed to global climate change. The principal greenhousegases are carbon dioxide (C02), methane (CH4), nitrous oxide (N20), sulfur hexafluoride (SF6),perfluorocarbons (PFCs), hydrofluorocarbons (HFCs), and water vapor (H20). CO2 is thereference gas for climate change because it is the predominant greenhouse gas emitted. Projectconstruction would result in greenhouse emissions, primarily CO2, emitted by trucks andearthmoving equipment. The consumption of fossil fuels to generate electricity to operateproposed project components would create greenhouse gas emissions during operations.

2.2 Regulatory Setting
In September 2002, Governor Gray Davis signed Assembly Bill (AB) 1493 requinng thedevelopment and adoption of regulations to achieve "the maximum feasible reduction of
Alondra Community Regional Park Upgrades ProjectIS/MNO Addendum
2-1 ESA 1206454.02June 2008
Innial Study Addendum
greenhouse gases" emitted by noncommercial passenger vehicles, light-duty trucks, and othervehicles used primarily for personal transportation in the State. In 2005, in recognition of
California's vulnerability to the effects of climate change, Governor Schwarzenegger establishedExecutive Order S-3-05, which sets forth a series of target dates by which statewide emissions ofgreenhouse gas would be progressively reduced, as follows:
C .
. By 2010, reduce greenhouse gas emissions to 2000 levels;
. By 2020, reduce greenhouse gas emissions to 1990 levels; and
. By 2050, reduce greenhouse gas emissions to 80 percent below 1990 levels.
In response to Executive Order Executive Order S-3-05, the Secretary of the CaliforniaEnvironmental Agency (Cal EP A) created the Climate Action Team (CAT), which, in March2006, published the Climate Action Team Report to Governor Schwarzenegger and the
Legislature (the "2006 CAT Report"). The 2006 CAT Report identifies strategies that the Statecould pursue to reduce climate change greenhouse gas emissions. These are strategies that couldbe implemented by various State agencies to ensure that the Governor's targets are met and canbe met with existing authority of the State agencies.
, .
~ ::
( -
In June 2007, California Air Resource Board (CARB) directed staff to pursue 37 early actions forreducing greenhouse gas emissions under the California Global Warming Solutions Act of 2006
(AB 32.) The broad spectrum of strategies to be developed - including a Low Carbon FuelStandard, regulations for refrigerants with high global warming potentials, guidance andprotocols for local governments to facilitate greenhouse gas reductions, and green ports - reflectsthe seriousness of the threat of climate change and the need for action as soon as possible (CARB,2007a). CARB staff has evaluated all 48 recommendations submitted by several stakeholder andseveral internally-generated staff ideas, which were published in the Draft List of Early ActionMeasures To Reduce Greenhouse Gas Emissions In California Recommended For BoardConsideration in September 2007 (CARB, 2007b). Based on its additional analysis, CARB staff isrecommending the expansion of the early action list to a total of 44 measures. These measures arepresented in Table 2.1.
i.
r -
The 2020 target reductions are currently estimated to be 174 miIlion mettic tons of CO2 equivalent
(MMTC02E). In total, the 44 recommended early actions provided in Table 2.1 have the potentialto reduce greenhouse gas emissions by at least 42 MMTC02E emissions by 2020, representingabout 25 percent of the estimated reductions needed by 2020. CARB staff is working on 1990 and2020 greenhouse gas emission inventories in order to refine the projected reductions needed by2020 and expects to present its recommendations to CARB by the end of 2007. The 44 measuresaddress various sectors, including fuels, transportation, forestry, agriculture, education, energyefficiency, commercial, solid waste, cement, oil and gas, electricity, and fire suppression.

requirements of AB 32. These regulations are expected to require reporting for certain types offacilities that make up the bulk of the stationary source emissions in California.
Alondra Community Regional Park Upgrades ProjectIS/MNO
2-3 ESA 1206454.02.September 2007
Initial Study Addendum
Currently, the draft regulation language identifies major facilities as those that generate more than25,000 metric tons of CO2 per year (C02/yr.) This reporting limit is consistent with EuropeanUnion reporting limits. Cement plants, oil refineries, electric generating facilities/providers,co-generation facilities, and hydrogen plants and other stationary combustion sources that emitmore than 25,000 MT C02/yr, make up 94 percent of the point source CO2 emissions inCalifornia (CARB, 2007c).
In May 2008, the Californa Department of Justice published the California Environmental QualityAct Addressing Global Wanning Impacts at the Local Agency Level to assist local agencies withimplementing duties under CEQA as they relate to global wanning. Included in this document arevarious measures that may reduce the global warming related impacts of a project. As appropriate,the measures can be included as design features of a project, required as changes to the project, orimposed as mitigation (whether undertaken directly by the project proponent or funded bymitigation fees). The measures set forth in the document are examples; the list is not intended to beexhaustive.
~ :.
2.3 Impacts and Mitigation Measures
Significance CriteriaThe criteria used to determine the significance of the proposed project's greenhouse emissionsresulting from construction and operation are as follows:
(a) Conflict with the state goal of reducing greenhouse gas emissions in California to 1990levels by 2020, as set forth by the timetable established in AB 32, California GlobalWarming Solutions Act of 2006.
Project Impacts (Construction and Operation)Construction is scheduled to begin in late summer/fall 2008, and would continue forapproximately 20 months. Construction of the proposed project would generate greenhouse
emissions from demolition, excavation, and construction activities. Greenhouse emissions werecompiled using URBEMIS 2007 (version 9.2.4), which is an emissions estimation/evaluationmodel developed by CARB, as well as the General Reporting Protocol of the California ClimateAction Registry, and latest global warming potentials of the International Panel on ClimateChange. Appendix A provides details of the URBEMIS outputs for both construction andoperational emissions. As provided in Appendix A, the emissions of CO2 from constructionwould be approximately 5,963 pounds per day (Ib/day) or 445 tons per year (tpy). Thisinfonnation is consistent with the CO2 emission data provided on page 2- 1 0 of the previouslycirculated IS/MND. In addition, the URBEMIS outputs provided in Appendix A show the highestdaily emissions of CO2 from project operations to be i 50 lbs/day or 29 tpy. This information isconsistent with the CO2 emission data provided on page 2- 11 of the circulated IS/MND. Project-related emissions of greenhouse gases are presented in Table 2.2 below. As shown, COzEemissions are approximately 65 tpy during construction and 210 tpy for project operations.

The greenhouse gas emissions of the project itself would not result in climate change constitutingan adverse environmental effect. Rather, it is the increased accumulation of the project'sgreenhouse gas in the atmosphere together with greenhouse gas emissions world-wide that mayresult in global climate change, the consequences of which may result in adverse environmentaleffects. It is not possible to predict the specific impact, if any, to global climate change from therelatively small incremental increase in emissions associated with one general developmentproject.
The proposed project would comply with applicable laws and regulations for reducinggreenhouse gas emissions that may be in place at the time of project construction and operation,including without limitation building code and vehicular regulations. The proposed project wouldcomply with building code standards and other applicable greenhouse gas reduction regulationsas they are adopted and implemented.
L
In addition, the project is consistent with the greenhouse gas reduction strategies that have beenadopted or recommended by CAT or CARB as of the date of this analysis. The consistency of theproposed project with the strategies from the 2006 CAT Report is evaluated in Table 2.3. Asshown from the analysis above, while most of the CAT recommended strategies are not directlyapplicable to an individual development project, the project is consistent with applicablestrategies, would not obstruct or conflict with any of these strategies, and would implement manyof the underlying goals of the strategies that do not directly apply to the project. As a result, theproject would be consistent with the feasible and applicable strategies identified by CAT.

SOURCES: Climate Action Team, 2006.
Given the lack of guidance from the State of California and the CEQA Guidelines on thresholdsfor assessing the impact of greenhouse gas emissions, three considerations will be used todetermine whether the project could be in conflict with the state goals for reducing greenhousegas emissions. These considerations were developed from a review of recent publications andactions from CARB that address how the state plans to achieve the goals of reducing greenhousegas. i The considerations are shown directly below and include a review of:
A. The potential conflicts with the 44 early action strategies identified by CARB;
B. The relative size of the project in comparison to the estimated greenhouse reduction goal of174 MMTC02E by 2020 and in comparison to the size of major facilities that are requiredto report greenhouse gas emissions (25,000 metric tons of C02E/yr)2; and
C. The basic parameters of a project to determine whether its design is inherently energyefficient.
With regard to Item A, the project does not pose any apparent conflict with the most recent list ofthe CARB early action strategies as provided in Table 3.3.
With regard to Item B, operation of the proposed project would result in approximately 210
metric tons of C02E/yr. Project emissions would be much lower than the reporting limit of25,000 metric tons ofC02E/yr.
Regarding Item C, the proposed project would be designed and built to include aspects, such asmaximizing operational efficiency through the reduction of energy consumption, as feasible. Forexample, the instalJation of energy star labeled roofing materials, light-colored roofing materialsto deflect heat away from buildings, and the use of double-paned windows to reduce thermal lossin buildings, wilJ be considered in the design of the proposed project.

While the foregoing analysis provides a calculationof greenhouse gas emissions and consistencyanalysis with applicable policy and regulations, it is not possible to quantify the project's project-
specific impact upon climate change and global warming. Nor is it possible to quantify the ex~entto which the project wil reduce greenhouse gas emissions that would otherwise occur in itsabsence. At this time, there are no generally accepted project-specific criteria for evaluating whatconstitutes a project-specific impact with respect to greenhouse gas emissions or global climatechange. Strategies for reducing greenhouse gases are evolving, and new laws and regulationsaimed at reducing emissions are expected. The project would be built over a 20-month period andwould comply with applicable laws and regulations, including vehicular and building regulations,in effect at the time the project is constructed. Project greenhouse gas emissions are expected tobe further reduced as local governents implement various strategies to further reducegreenhouse gas emissions.
,t...':
Project Impact:
The proposed project's impacts to greenhouse gas emissions from construction and operations areless than significant.
Mitigation MeasuresNo mitigation measures are required.
2.4 Conclusions
As discussed in Section 2.2, the project does not pose any apparent conflict with the most recentlist of the CARB early action strategies as provided in Table 3.3. In addition, the COzE emissionswould be much lower than the reporting limit of 25,000 metric tons of C02E/yr. In addition, theproposed project would be designed and built to include green building aspects, such asmaximizing operational efficiency through the reduction of energy consumption, as feasible. Theproject would be built over a 20-month period and would comply with applicable laws andregulations, including vehicular and building regulations, in effect at the time the project isconstructed. Project greenhouse gas emissions are expected to be further reduced as localgovernments implement various strategies to fuher reduce greenhouse gas emissions.
,
.íc=
As a result, the proposed project's impacts to greenhouse gas emissions from construction andoperations are considered less than significant. The conclusions in this IS/MND addendum areconsistent with the conclusions provided in the previously circulated IS/MND and provides afactual basis that the proposed project will not have a significant effect on the environment withthe implementation of additional mitigation measures. As such, in accordance with CEQASection 1 5063( c)( 5), the previously circulated IS/MND and associated addendum presents theappropriate level of analysis.

CHAPTER 1Executive Summary
1.1 Introduction
BackgroundThe Los Angeles County Deparent of Public Works (LACDPW) (applicant) is proposing toupgrade the facilities located within Alondra Community Regional Park, also referred to as"Alondra Park" or "proposed project". The improvements for Alondra Park, located in Lawndalewithin an unincorporated area of Los Angeles County, are required to upgrade facilities in need ofrepair. The recreational services provided by Alondra Park are administered by the County of LosAngeles Deparent of Parks and Recreation, which manages over 63,000 acres of parks,gardens, lakes, trails, and natual and recreational areas in Los Angeles County (DPR, 2007a).LACDPW, responsible for capital projects for various County departents, is the projectapplicant (LACDPW, 2007).
Alondra Park encompasses approximately 84 acres of land and includes a children's play area, anurban lake, gymnasium, lighted baseball/softball fields, multipurose room with kitchen, picnicareas with barbeque braziers, a swimmng pool (curently unused), and a volleyball cour. Mostof the facilties to be renovated were constructed in the early 1960s have exceeded theiruseful life. The improvement would be located to the north of the existing parking lot onapproximately 1.5 acres and would include redevelopment of the existing swimming pool andpicnic area and constrction of a new pool house, water play area, recreational office, andskateboard park. The proposed project would meet the requirements of the Americans withDisabilities Act (ADA).
Impact MethodologyIn accordance with the California Environmental Quality Act (CEQA), projects which havepotential to result in either a direct physical change in the environment, or a reasonablyforeseeable indirect physical change in the environment, must undergo analysis to disclose thepotential significant effects.I,2 The provisions of CEQA apply to all California governentalagencies at all levels, including local agencies (such as LACDPW), regional agencies, stateagencies, boards, commissions, and special districts. As the applicant and lead agency for theproposed project, LACDPW has the principal responsibilty for conducting the CEQA

sea at San Pedro Harbor. The Alondra Park Gold Course is located to the nort and west,followed by commercial and residential land uses a~ross Prairie A venue. Land uses to the northinclude low-density residential development across Manhattan Beach Boulevard. Alondra ParkReservoir is located adjacent to the norteast.
Access and Parking1-405 and California Highway 107 are located to the west of the park. Primary access to the site islocated at the intersection of Yukon Avenue and Redondo Beach Boulevard, which providesentrance to the parking lot containing an ample number of spaces. From the parking lot, an accesspoint is provided as paved stairs form a sidewalk that continues around the pooL. The sidewalks
continue around the park perimeter and pedestrans have the option of accessing other aspects ofthe park, including the lake, by continuing on an adjoining sidewalk. The proposed project doesnot include any new access or additional parking.
1.3 Project Components and Design FeaturesThe proposed project components are demonstrated on the site plan (Figure 4). The park
redevelopment and improvement areas are located to the north of the parking lot and consist of aswimng pool, pool house, water play area, recreational offce, skateboard park, picnic area, andrestroom building. The applicant has proposed the following improvements:
. Demolish the existing restroom building and chlorine building, both located in thewestern area of the project site adjacent to the current play area;
. Redevelop the swimming pool to be a competitive swiming, diving, and water polo
training pool (approximately 25 yards x 25 meters);
. Constrct lifeguard towers adjacent to and surrounding the pool;
. Constrct a pool house/recreation offce which would be approximately 6,000 square feet
and would include a public counter, staff control area with an offce, a conference area,interior and exterior restrooms, changing rooms, and storage;
. Create a water play splash area which would be approximately 4,000 square feet with
multiple interactive featues. The water play/splash area would also be located within 100feet of the nearest restroom;
. Construct an in-ground skateboard park which would be approximately 14,000 square
feet and would have lighting and appropriate fencing; and
. Improve picnic areas with shade structures large enough to accommodate a group of
around 100 people and smaller shade structures that can accommodate approximately 16-20 people.
· Electrical service. security lighting and grils would be provided at the designated Vicnic
area.

1.4 Grading and Construction Program
Constrction would begin in August 2008 and would continue for approxiately 20 months.Initially, the existing restroom buildings would be demolished followed by redevelopment of theswimmng area. The swimming pool, bathhouse, and associated fencing would be demolishedalong with the chlorine buiiding in the western area of the site adjacent to the play area.Additional demolition would include curbs, walkways, and entr steps (access area off of theexisting park lot). The last phase would include the construction of the pool house! recreationaloffce, the new swimmng pool, the water play splash area, restrooms, and in-ground skateboardpark along with auxilary uses.
For each phase, grading would be implemented as required to re-grade distubed areas, to providedrainage, and to allow for utility upgrades. Due to the flat topography, grading for the projectwould be minimal and earth would be stockpiled on-site for reuse. It is anticipated thatapproximately 10.000 cubic yards of soils wil be required for fill materiaL. Where possible,existing landscaping and open areas would be conserved by leaving the areas in their curentcondition.
1.5 Project Objectives
The applicant's objectives for the project include the following:
. Redevelop an exiting recreational facilty to meet ADA requirements including
modifying restroom facilities, walkways, etc.;
. Provide a quality, up-to-date recreational facility that meets the growing demands of the
area;
. Respond to the need for expanded and enhanced community recreational amenities;
. Redevelop outdated and old recreational offerings; and
. Conserve open space and recreational areas within the County.
1.6 Areas of Known ControversyThrough this process, no key issues or areas of controversy were identified. The CEQA analysisprovided mitigation measures that reduced potentially significant impacts to less than significant.

Discussiona) No Impact. The proposed project includes the redevelopment of the southwestern portion
of Alondra Community Regional Park. Curently, the project site contains a walkingpath, a fenced empty swimming pool, an urban lake, a children's play area, restroomfacilities, a picnic area with benches, and an open area for volleyball (refer to PhotoDocumentation in Appendix A for photos of the existing Alondra Park facility). Asdepicted in Figue 4 Site Plan, the park renovations would include a new swimming pool,pool house, water play area, skateboard park, picnic area, and restroom building. Theproposed improvements would not dramatically change or alter the park's existingcharacter. The new structures would be less than one-story in height and would not blockviews for the area. The proposed recreational enhancements would not adversely affect ascenic vista. Therefore, no impact would occur.
b) Less Than Signifcant with Mitigation Incorporated. Alondra Park does not contain
scenic natural features such as rock outcroppings or historic buildings. According to theCounty of Los Angeles General Plan Draft Scenic Highways Map, the proposed site isnot located in an Adopted Scenic Highway or a Proposed Scenic Highway.3 The parkdoes contain several trees, such as the 13 mature ficus trees located at the entrance to the
south side of Alondra Park (Walter Warrner Consulting Arborist, 2007). The subjecttrees are a major component at the entrance to the park and figue prominently in the re-designing of the park (see Appendix B for Arborist Report). As recommended in theArborist Report, the ficus trees would be incorporated into the design or relocated aspossible, to accommodate park upgrades. The anticipated location of the trees to remainis provided on Figure 5.

As a result, Mitgation Measure AES -1 below is recommended to protect the subject trees andpreserve their aesthetic value for the facility. Impacts would be less than significant withimplementation of this mitigation measure.
Mitigation Measure
Measure AES-l: Protection of ficus irees during construction by implementing the
following:
. Determne the Critical Root Zone (CRZ) and Tree Protection Zone (TPZ) foreach individual tree or row of trees at the front of the park.
. Assure that construction activities, such as the movement of equipment and the
storage of materials on a constrction site, consider the CRZ and TPZ.
. Exceptional care should be taken when removing the concrete around the CRZ;
the concrete can be broken up mechanically but should be removed manuallywithout distubing the root mass underneath.
. Vehicular traffc over the entire site should be kept to a minimum and routed
away from trees (or the TPZ).
. Unnecessar traffc, such as workers' personal vehicles, should be prohibited onthe site and movement over the TPZ and CRZ by delivery vehicles should berestricted as much as possible.
. A storage area for constrction materials should be identified that is well away
from trees and located to minimize the traffc required to retrieve and use thematerials.
c) Less Than Signifcant Impact. The existing visual character represents that of arecreational facility. The intention of the proposed project would be to enhance andmodernize Alondra Community Regional Park. The upgrades are planned to improvefacilities that have deteriorated and are under utilized due to their present condition. Theproposed changes would improve recreational uses on-site and provide a benefit to thesurounding community. The views :fom the west of the site lookig east consist of thepark's fenced pool with the gymnasium building. Views from the east ofthe site lookingwest consist of the picnic area, portions of the fenced pool, and the volleyball area. Theview from the north of the site looking south consists of the fenced pool, adjacentchildren's play area, and the existing parking lot. The view from the south of the site, atthe entrance to the project site from the parking lot, provides an immediate visual of theproject site including the pool, restrooms, play area, volleyball area, and adjacent lake.The proposed project footprint falls within the already developed park. The new facilitieswould not negatively affect the existing visual character or quality of the site and itssurroundings. The proposed changes would update and improve the park facilities. Theredevelopment of the southern potion of Alondra Park would not have a significantimpact to the site or its surrounding area.

d) Less Than Significant Impact. Curent light sources include those related to commercial.,_and residential uses across from the park, as well as the existing security and landscapelighting on-site. Alondra County Golf Course is located to the nortwest of the projectsite with El Camno College located to the east adjacent to park and near the golf course.The proposed project would have security lighting añd lighting associated with theswim minI! pool and in-ground skateboard park. The skateboard park and swiminl!pool would have appropriate lighting associated with the recreational activity and wouldbe operated until approximately 9:00 pm. The lighting used would incorporate the latestapproved components to reduce glare. With the exception of securty lighting, all lightingwould conform to park hours. The amount of light and glare that would occur after thecompletion of the proposed park improvements would be similar to the existingconditions. Therefore, impacts to light and glare would be less than significant.

AGRICULTURAL RESOURCESIn determining whether impacts to agricultural resources are significant environmental effects, lead agencies may referto the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the CaliforniaDepartment of Conservation as an optional model to use in assessing impacts on agriculture and farmland,Would the project:
a) Convert Prime Farmland, Unique Farmland, or
Farmland of Statewide Importance, as shown on themaps prepared pursuant to the Farmland Mappingand Monitoring Program of the California ResourcesAgency, to non-agricultural use?
b) Conflct with existing zoning for agricultural use, or aWillamson Act contract?

Discussiona) No Impact. A project conflcts with or obstrcts implementation of the applicable air
quality plan if the project is incompatible with the South Coast Air Quality ManagementDistrict (SCAQMD) and the Southern California Association of Governents (SCAG)air quality policies. The assumptions for growth and associated air quality impacts havebeen established by SCAG, and these assumptions are utilzed in SCAQMD's Draft 2007Air Quality Management Plan (AQMP) (SCAQMD, 2006).
The proposed project is located in the South Coast Air Basin and SCAQMD isresponsible for the development of the regional AQMPs and efforts to regulate pollutantemissions from a variety of sources. SCAQMD developed the 2007 AQMP, which isdesigned to meet both state and federal Clean Air Act (CAA) planing requirements forall areas under SCAQMD jursdiction. The 2007 AQMP focuses on reduction strategiesfor ozone and particulate matter and sets forth procedures for measurements, control
strategies, and air quality modeling. To assure the goals and policies established in the2007 AQMP are maintained, ambient standards have been established for the followingcriteria pollutats: ozone (03), particulate matter less than 10 microns in diameter(PMlO) and less than 2.5 microns in diameter (PM2.5), carbon monoxide (CO), nitrogenoxides (NOx), sulfur dioxide (S02), and lead.
The Basin is a nonattainment area, or does not meet established ambient air qualitystandards, for 03 (for both the I-hour and 8-hour standards), PMlO, and PM2.5. TheCAA sets certain deadlines for meeting the NAAQS within the Basin including: I-hour03 by the year 2010; 8-hour 03 by the year 2021; and PM2.5 by the year 2015.

Initial Study
A project conflcts with or obstrcts implementation of the applicable air quality plan if theproject is incompatible with SCAQMD and the Southern California Association ofGovernents (SCAG) air quality policies. The proposed Project would conflct withSCAQMD and SCAG policies if it:
· Causes an increase in the frequency or severity of existing air quality violations;
. Causes or contrbutes to new air quality violations;
. Delays timely attainment of air quality standards or the interim emission reductions
specified in the SCAQMD's Air Quality Management Plan (AQMP); or
. Exceeds the assumptions utilzed in the SCAQMD's AQMP.
The project site is located within an area designated for open space land uses, and theproposed project is consistent with the curent land use and zoning designations. Theproposed project would not require a General Plan amendment related to land use, and assuch, would be consistent with applicable land use planning documents. This projectwould not directly result in population growth (e.g. housing development) and theproposed project would not result in an exceedance with the SCAG growth forecasts.Consequently, implementation of the proposed project would be consistent with AQMPattainment forecasts. In sumary, project development would not conflct with, or obstrctimplementation of the AQMP. As a result, there would be no impact.
b) Less Than Signifcant Impact. To determne if the proposed project would violate any airquality standard or contribute substantially to an existing or projected air quality violation,
6project specific impacts were compared to the following SCAQMD criteria:
· Constrction emissions from both direct and indirect sources would exceed any of
the following SCAQMD prescribed threshold levels: (1) 75 pounds per day(lbs/day) for ROC; (2) 100 Ibs/day for NOx; (3) 550 Ibs/day for CO; (4) 150Ibs/day for PM¡o or SOx, (5) 3 Ibs/day for lead, and (6) 55 Ibs/day for PMZ,5'
. Operational emissions from both direct and indirect sources would exceed any of
the following SCAQMD prescribed threshold levels: (1) 55 Ibs/day for ROC andNOx; (2) 550 Ibs/day for CO; (3) 150 lbs/day for PMIo or SOx (4) 3 Ibs/day forlead, and (5) 55 Ibs/day for PMz.5,
Construction EmissionsConstrction of the site would generate emissions from excavation and demolition
activities, as well as park upgrades. Construction activities are scheduled to begin inAugust 2008 and end in April 20 I 0, resulting in construction duration of approximately20 months. It is anticipated that approximately 10.000 cubic yards of soils wil berequired for fill materiaL. Mass daily emissions during construction were compiled
using URBEMIS 2002, which is an emissions estimation/evaluation model developed by
6 South Coast Air Quality Management District, CEQA Air Quality Handbook, Chapter 6 (Determining the AirQuality Signifcance of a Project), 1993.

PM10 emissions estimates are based on compliance with SCAQMD Rule 403 requirements for fugitive dust suppression,
SCAQMD's Final Methodology to Calculate PM2.5 Significance Thresholds (October 2006) requires the following: (1) fugitivesources - the PM2,5 fraction of PM,o is 21 percent (2) off-road combustions sources - the PM2,5 fraction is 89 percent (3) stationarycombustion sources, the PM2,5 fraction of PM10 is 99 percent
SOURCE: ESA, 2007b,
SCAQMD Rule 403 requires that fugitive dust be controlled with best available controlmeasures so that the presence of such dust does not remain visible in the atmosphere
beyond the propert line of the emission source. The construction activities would
comply with applicable SCAQMD Rule 403 provisions during project constrction are asfollows:
· All disturbed areas, including storage piles, which are not being actively utilized
for constrction puroses shall be effectively stabilized of dust emissions usingwater, chemical stabilzer/suppressant, covered with a tarp or other suitable coveror vegetative ground cover.
· All on-site unpaved roads shall be effectively stabilized of dust emissions using
water or chemical stabilizer/suppressant.

. Limit traffc speeds on unpaved roads to 15 mph.
. Suspend excavation and grading activity when winds exceed 20 mph.
. If possible, use alternative fueled or catalyst equipped diesel equipment.
. Minimize idling time (e.g., 10 minute maximum) and limit the hours of operationof heavy duty equipment and/or the amount of equipment in use.
Operational Emissions
Emissions from project operations include those resulting from traffic trips in the projectarea and associated air pollutant emissions. The proposed park upgrades could result inadditional employees or additional patrons at the park facilty, but not to significantlevels. To determne project level impacts, operational emissions generated by mobilesources were quantified to demonstrate emissions resulting from project specificactivities during occupation (which represents both pre- and post project conditions).Criteria pollutant emissions were calculated using the URBEMIS 2002 emissionsinventory model, which multiplies an estimate of daily vehicle miles traveled byapplicable Emfac2002 emissions factors. The URBEMIS 2002 model assumed a targetbuild out year of 2010. As shown in Table 2.2, net regional emissions resulting from theproposed project operations would not exceed regional SCAQMD thresholds for ROC,NOx, SOx, CO, PMZ5 or PMIo.

for 2020 based on 1990 emission levels and to adopt mandatory reporting rules forsignificant sources of GHGs. In addition to regulated air pollutats provided in Tables 2and 3, the proposed project would result in emissions of the greenhouse gas carbon
dioxide (C02) as a byproduct of combustion of gasoline and diesel fuel in constrctionequipment and constrction worker commute -trps and from vehicle trips related tooperations. In addition, the increased demand for electrical energy by the proposedproject may result in an increase of C02 emissions from those off-site sources of energy
(referred to as indirect emissions, since they are not directly emitted by the facilityoperations). The significance of the proposed project's C02 emissions cannot bedetermned without substantial speculation. As there are no criteria at this time toevaluate the significance of the GHG emissions, no conclusion can be reached regardingthis potential impact. In accordance with Section 15145 of the CEQA Guidelines, anypotential impact regarding GHG emissions is too speculative for evaluation and nofurther discussion of this potential impact is required.
c) Less Than a Significant Impact. According to the SCAQMD CEQA Air Quality
Handbook, projects that are consistent with the AQMP performance standards andemission reduction targets would be considered less than significant cumulatively, unlessthere is other pertinent information to the contrar. Specifically, the handbook identifies
three possible methods to determne the cumulative significance of land use projects
(SCAQMD, 1993). As shown, on Table 2.2, the proposed project would not result in asignificant increase in operational emissions as compared to existing conditions. Asprovided in Table 2.1, construction impacts would be less than the SCAQMD's establishedthresholds. According to the SCAQMD CEQA Air Quality Handbook, projects that areconsistent with the AQMP performance standards and emission reduction targets would beconsidered less than significant unless there is other pertinent information to the contrary.As provided in impact discussion C.(a) above, the proposed project is consistent with the2007 AQMP performance standards and emission reduction targets. As a result, impactsare less than significant.
d) Less Than a Signifcant Impact. Some population groups, such as children and theelderly, are considered more sensitive to air pollution than others. The project is locatedwithin an area that contains residential development to the north and east. The nearestschool is the Evelyn Carr Elementary School, located at 6404 West 168th Street inTorrance (0.6 mile south). Criteria pollutants such as particulate matter can result from avarety of construction activities and such pollutants can affect sensitive receptors. As
provided in C.b) above, emissions from construction and operations are less than thesignificance thresholds provided by the SCAQMD. As such, impacts are considered lessthan significant.
e). Less Than Signifcant Impact. Potential sources that may emit odors during
construction activities include the use of architectural coatings and solvents. SCAQMDRule 1113 limits the amount of volatile organic compounds from architectural coatingsand solvents. The constrction period is anticipated to occur for a period of 20 months,

and the quantity of coating and solvents anticipated for use are minimaL. In addition, viamandatory compliance with SCAQMD Rules, no constrction activities or materials areproposed which would create objectionable odors that exceed applicable thresholds. Theproject operations would not create objectionable odors. As such, impacts arè less than

Discussiona) Less Than Signifcant Impact with Mitigation Incorporation. The proximity of
Alondra Park to the ocean and an urban river, together with its lake, meadow lawns, andwoodlands, contributes to the park fuctioning as a naturally landscaped habitat and
environment for migratory wetland and upland birds. The island in the lake has aCalifornia native plant garden that is also an attractant for native butterfies and wildbirds that migrate from Santa Catalina Island and the Palos Verdes Peninsula (DPR,2007b ).

Initial Study
A California Natual Diversity Database (CNDDB) query was performed for the projectarea to determne if habitat exists that supports species identified as a candidate,sensitive, or special-status species in local or regional plans, policies, or regulations, orby the Catifornia Deparment of Fish and Game or U.S. Fish and Wildlife Servicesquadrangle (CDFG, 2006).8. Based on the CNDDB search of this 'quadrangle, there are12 special-status species with the potential to occur in the vicinity of the project site,either as residents or transient animals.9 However, based on known records from theCNDDB, habitat affinities of the species, a reconnaissance-level surey of the site by anESA biologist on Februar 7, 2007 and professional judgment, none of these specieslisted in Table 2.3 would occur on the areas of the project site where construction wouldoccur. Given the lack of suitable habitat specific to the project area where improvementswould be implemented (e.g. pool area), impacts to species listed in Table 2.3 would notoccur.
There are several mature trees on-site, which could harbor nesting birds durng matingseasons. During construction, tree distubance or removal activities have potential todisrupt nesting birds if they occur. Due to the urbanized character of the area, raptornesting and foraging as well as bat roosting and foraging would likely not occur becauseraptors and bats generally require suffcient open space areas for these puroses. Ifconstruction activities were to cause the direct mortality or indirectly affect (e.g., treeremoval, constrction noise, and dust causing nest abandonment) to non-status nestingmigratory birds, this would be a violation of the federal Migratory Bird Treaty Act
(MBT A). Though variable, the tyical nesting season occurs between the months ofFebruary to August each year. Constrction activities would occur from August 2008 toApril 2010. As such, impacts could potentially occur durng project constrction ifnesting birds do exist. During constrction, personnel would implement efforts toconform with MTBA requirements. As operations could potentially occur in a manersimilar to existing conditions, no significant impacts are anticipated. To assure thatMBT A violations do not occur, construction workers would implement MitgationMeasure BIO-I to determine occupancy status or continuing nest dependency:
Mitigation Measure

· A preconstrction nesting bird survey for all breeding bird species shall beconducted in a manner to assure construction-related mitigation activities can beimplemented appropriately.
8 The project site is located in the U.S. Geological Survey (USGS) Inglewood 7.S-minute quadrangle and a California
Natural Diversity Database (CNDDB) query was perfonned for this quadrangle,9 The tenn "special-status" species includes those that are listed and receive specific protection defined in federal or
state endangered species legislation, as well as species not fonnally listed as Threatened or Endangered, butdesignated as Rare or Sensitive on the basis of adopted policies and expertise of state resource agencies ororganizations, or policies adopted by local agencies such as counties, cities, and special distrcts to meet localconservation objectives,

. Sureys shall be conducted within all potential breeding habitat located within250 feet of the project site.
. If constrction activities are delayed or are suspended for more than 30 days after
the initial pre-constrction surey, an additional nesting bird surey must beconducted per item #1 above, prior to the start or re-initiation of construction-related activities.
. If an active nest is located within 250 feet of proposed constrction activities, the
proponent in consultation with CDFG wil determne the appropriate protectivemeasures. This consultation can be made by a conference telephone call, an on-site
meeting, or other mutually agreeable means.
b) No Impact. Based on site reconnaissance and information provided by the USGSInglewood topographic map (USGS, 1964), it was determined that the project site doesnot contain riparian habitat. Riparian habitat is lowland habitat associated with the bedand banks of a river, stream, or wash. The CNDDB does not identify any sensitive natualriparan communities tracked by the CDFG that could occur within the project's vicinity
(CDFG, 2006). Therefore, the proposed project would not have a substantial adverseeffect on any riparian habitat or other sensitive natual community identified in local orregional plans, policies, regulations or by the California Deparent of Fish and Game orU.S. Fish and Wildlife Service and there would be no impact.
c) No Impact. Based on site reconnaissance and information provided by the USGS, the
area to be improved does not contain federally protected wetlands as defined by Section404 of the Clean Water Act (e.g. blue line streams, marsh, vernal pool, coastal, etc.). Theproject footprint is located in an upland area that contains nonnative ornamental trees,shrbs, and ground cover and, therefore, riparian habitat is not present. The proposedproject site is not located within an area that possesses the proper vegetation (i.e., apreponderance ofhydrophytes or "water-loving" plants), soils (i.e., hydric or waterloggedsoils), or hydrologic conditions (i.e., inundated either permanently or periodically orsaturated during the growing season of the prevalent vegetation) to be defined as a
wetland according to the U.S. Army Corps of Engineers' (USACE) Wetlands DelineationManual (USACE, 1987). Therefore, the proposed project would not have a substantialadverse effect on federally protected wetlands as defined by Section 404 of the CleanWater Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through directremoval, fillng, hydrological interrption, or other means; and there would be no impact.
d) Less Than Significant Impact. The proposed project site is a park surrounded byresidential neighborhoods and is not connected to adjacent open spaces and, therefore,terrestrial wildlife movement to and from the park is severely limited if not completelysevered. Additionally, no streams or rivers occur within the area to be improved with the

new park facilities. Therefore, fish movement does not occur within the project footprint.Given the lack of native habitat present within the project footprit, it does not appear topossess the suitable habitat to act as a native wildlife nursery site (also see response toBiological Response D.a above). It is possible that migratory birds could utilze the site
. for nesting puroses. However, with incorporation of Mitgation Measure BIO-I, the. proposed project would not significantly affect a native 'wildlife nursery site, if present.
Therefore, the proposed project would not intedere substantially with the movement ofany native resident or migratory fish or wildlife species or with established native
resident or migratory wildlife corrdors, or impede the use of native wildlife nursery sites,and there would be a less than significant impact.
e) No Impact. An ESA biologist performed a reconnaissance-level survey of the site onFebruary 7, 2007. The proposed project does not contain any native oak trees that wouldbe protected under the Los Angeles County Oak Tree Ordinance. There are no otherapplicable local policies or ordinances designed to protect biological resources that wouldconstrain development of the site. Therefore, the proposed project would not conflct withany local policies or ordinances protecting biological resources, such as a tree preservationpolicy or ordinance, and there would be no impact.
There are several matue trees, as well as natual and ornamental vegetation, located
throughout the site. Constrction activities would include landscape and irgation systemsreplacement and replanting of existing vegetation with native / drought tolerant species asapplicable. As discussed in Response A.b) of the Aesthetics impact discussion, the parkdoes contain several trees, such as the 13 matue ficus trees located at the entrance to thesouth side of Alondra Park (Walter Warner Consulting Arborist, 2007). The subject treesare a major component at the entrance to the park and figure prominently in the re-designing of the park. As provided in Mitigation Measure AES -1, of the Aestheticssection, mitigation measures would be incorporated to protect the subject ficus trees. As aresult, the impacts to this biological resource would not occur. The Arborist Report isprovided in Appendix B.
f) No Impact. The proposed project is not located within a federally adopted HabitatConservation Plan (HCP) or Natural Community Conservation Plan (NCCP) or within anyother approved local, regional, or state habitat conservation plan. Therefore, the projectwould not conflict with the provisions of an adopted HCP, NCCP, or other approved local,regional, or state habitat conservation plan at this time, and there would be no impact.

b-d) Less Than Signifcant Impact with Mitigation Incorporated. There are no knownarchaeological, paleontological, or unique geological features on-site. The project site is adisturbed area in a development community. To assure that impacts remain less thansignificant, Mitigation Measure CUL-I would be implemented. If during grading anyhuman remains are found, construction activity in the immediate area would cease andthe County Comer would be contacted. Incorporation of Mitigation Measure CUL-2 wilreduce these potential impacts to less than significant.

Discussiona - i) Less Than Signifcant Impact. The project site is located within Southern California
seismically active region. Primar ground rupture or, fault rupture is defined as surfacedisplacement, which occurs along the surface of a fault durng an eartquake. The nearestdominant fault featue in the vicinity is the northwest trending Newport Inglewood FaultZone (NIFZ), which is located about three miles to the east of the project site. The NIFZis an uplifted anticlinal strcture broken up by a series of offset, parallel faults.Movement along the NIFZ has resulted in formation of the string of low hils that extendfrom the Baldwin Hils southeastward to Newport Beach. In addition to this fault, twosmaller faults, the Overland and the Charnock Faults, parallel the NIFZ to the southwest.As provided in the Geotechnical Study (see Appendix D), no known active or potentiallyactive fault traces have been recognized as crossing any part of the proposed project andCalifornia Geological Survey (CGS) does not delineate any part of the project area as

being within an Alquist-Priolo Earhquake Fault Zone (URS, 2007). In addition, theproject would not place additional strctures or people in an active fault zone. The projectwould not result in a significant increase in employees or visitors, thus the exposurewould be simlar to existing conditions. The project would not be expected to exposepeople or strctues to ruptue of a known e,arthquake fault. Impacts would be less than
significant.
a - ii) Less Than Signifcant Impact. As mentioned in Response F.a-i above, the project siteis located within the seismically active region of southern California. The Newport-Inglewood fault is the most significant seismic source to the site. At its closest, theNewport-Inglewood fault zone passes about 3 miles (5 km) to the norteast (URS, 2007).As with other developments in the region, the project could be subject to moderate tostrong ground shaking during seismic events. However, the project would not expose on-site employees and visitors to substantial new adverse effects related to strong seismic
ground shaking. As such, impacts are less than significant.
a - iii) Less Than Signifcant Impact. Liquefaction is a phenomenon where soils lose their
strength due to strong seismic shaking. Liquefaction tends to occur in saturated, loosesandy soils with a high groundwater table (50 feet or less below ground surace). A rapidincrease in groundwater pressures (excess porewater pressures) causes a loss of shearstrength. The primar secondar effects of liquefaction include sand boils, settlement andsettlement-related downdrag on deepened foundation systems, lateral spreading, and flowslides in areas with sloping ground. Based on the Seismic Hazard Map for the Inglewood
Quadrangle, the project site is not located within a Liquefaction Hazard Zone (URS,2007). Furher more, subsurace investigation indicates that the site is underlain bymostly stiff clay soil that is not prone to liquefaction. Therefore, liquefaction potential atthe project site is considered to be low. The site has been operating as a public parkfacility for several years, and no known issues related to liquefaction have occured. Assuch, impacts are assumed to be less than significant.
a - iv) Less Than Significant Impact. Landslides typically occur in steep slope areas. There
are no steep slopes or areas prone to landslide on-site. In addition, no substantial changein ruoff, which could induce landslides in steep sloped areas, is expected. In addition,the Seismic Hazards Zone Map for the Inglewood Quadrangle indicates that the projectelements do not lie within areas designated as having the potential for earhquake-induced land sliding (URS, 2007). The applicant would be required to incorporate bestmanagement practices (BMPs) to control water erosion and would be required to complywith standard County and Los Angeles Regional Water Quality Control Boardrequirements to limit erosion during construction. As the area topographically is not
indicative of a landslide area, impacts would be less than significant.
b) Less Than Significant Impact. Construction would begin in August 2008 and would
occur for approximately 20 months. As discussed in item a-iv above, BMPs to minimizestormwater pollution runoff would be implemented during constrction. For each phase,

grading would be implemented as required to re-grade disturbed areas, to provide ."drainage, and to allow for utilty upgrades. Due to the flat topography, grading for theproject would be miimal and earh would be stockpiled on-site for reuse. Theimplementation of BMP requirements would assure that the proposed project would notresult in substantial soil erosion or the loss of topsoiL. As such, impacts are less thansignificant.
c) Less Than Signifcant Impact. As indicated above, there is no potential liquefactionhazard within the project boundary. The project site curently operates as a
recreational/park facility, and unstable soils are not known to occur. The project area isnot located on a fault line, or in an area that would become unstable as a result of theproject, and potentially result in on- or off-site landslide, lateral spreading, subsidence,liquefaction, or collapse. Thus, impacts related to unstable geologic unit or soils would beless than significant.
d) Less Than Significant Impact with Mitigation Incorporated. Based on thePreliminary Geotechnical Study (URS, 2007) a significant amount of fill materials wouldneed to be imported to backfll the existing swimming pool to create the building pad.The minor amount of materials to be generated from excavations would consist of clayeyalluvial deposits. Based on the clayey nature of the on-site material, a medium to highexpansive potential should be assumed. To assure that impacts remain less thansignificant, Mitigation Measure GEO-I would be implemented.
Mitigation MeasuresMeasure GEO-1: If the clayey excavated soils were to be re-used in compacted fill,thorough mixing with coarse grain fill materials wil be necessary. The resulted mixshould have a maximum of 35 percent of fines passing a standard No. 200 sieve and anexpansion index not exceeding 30. The mix should be confirmed and approved by theGeotechnical Engineer of Record for their suitability before placing.
e) No impact. The Project site is located in an area served by existing sewer infrastrcture.Project construction does not include the installation of septic systems or otherwastewater disposal systems. No impacts would occur.

Discussiona-b) Less than Significant Impact. The proposed project would not transport, use, or dispose
of significant amounts of hazardous materials. Grading and construction activities mayinvolve the limited transport, storage, use, or disposal of hazardous materials from thefueling or servicing of construction equipment on-site. However, these activities wouldbe minimal, short-term, or one-time in nature. Due to the ae:e of the structures. thestructures to be removed could contain asbestos containine: material (ACM) or lead-based paint (LBP). These materials would be handled in accordance with the
applicable ree:ulations. resultine: in a less than sie:nifcant impact durine:construction. Once construction is complete, the park would utilize ordinar householdor general commercial cleansers, solvents, and other substances utilzed for cleaning andmaintenance of recreational facilities (i.e. restrooms, etc.). Use of such substances issubject to the regulations on the labels and as such would not result in significantimpacts. Therefore, the proposed park redevelopment would generate less than significantimpacts.
c) Less than Signifcant Impact. There are two schools located to the south of Alondra
Park within approximately one-quarter mile of the proposed project site: YukonElementary school located at 17815 Yukon Avenue and Evelyn Carr Elementary School

located at 6404 West 168th Street. Surounding schools beyond the one-quarter milesperimeter include Calvar Chrstian Academy located at 2818 Manattan BeachBoulevard and Casimir Middle School both located to the southwest of the project site,with Anderson Elementar School located to the north of the site on 4130 West 154thStreet. The park redevelopment would not involve the use of hazardous materials, acutelyhazardous materials, substances, or wastes in suffcient quantities to pose a hazard. Theproposed park redevelopment would be required to comply with all federal, state, andlocal rules and regulations for hazardous materials handling to ensure that impacts wouldbe less than significant.
d) Less than Signifcant Impact. Historically, the project site has operated as a park andthere are no known occurences related to hazardous waste or material storage, or related
activities resulting in waste generation or storage on-site. Thus, project constrction andoperation would not expose people to hazardous material or waste on-site. Therefore, theproposed project would have less than a significant impact.
e) Less Than Signifcant Impact. The proposed park redevelopment is locatedapproximately two and a half miles south of the Hawthorne Municipal Airport. Theairport is located between West El Segundo Boulevard and 120th Street. The Compton!Woodley Airport is located approximately four miles east from the project site and islocated on the comer of Alondra Boulevard and South Central A venue. The proposed
project is a redevelopment of existing recreational propert and is not located within twomiles of an existing public airport. Therefore, the proposed project would not pose asafety hazard for people working or residing in the project area.
f) No Impact. The proposed redevelopment of Alondra Community Regional Park is not
located in the nearby vicinity of a private airstrip. Please see Response G.e for details onthe location and proximity of airports. Therefore, the proposed redevelopment wouldhave no adverse impact.
g) Less than Significant Impact. The proposed Alondra Park redevelopment would not
intedere with current emergency response plans or emergency evacuation plans for local,state, or federal agencies. Please see Public Services, response "a" and response "b" forfurther details.
h) Less than Significant Impact. Alondra Community Regional Park is located in a
development community in Los Angeles County. Fire Protection services are provided tothe park by Los Angeles County Fire Department, Fire Station #21. The proposed projectwould include replacement of the existing BBQ grills. Appropriate signage would beposted to regulate the proper use of the BBQ grills. The park redevelopment would notincrease the potential for wildfires or expose people to wildfire dangers. The proposedredevelopment would have less than significant impacts.

Mitigation Measure HYD-I confirms .general statewide requirements that, prior toissuance of development permts project, the Applicant must prepare a Storm WaterPollution Prevention Plan (SWPPP), including appropriate BMPs (Best ManagementPractices) to prevent non-point source pollutats from leaving the project site and
reaching the water body of concern. Development permits are tyically issued after theApplicant has defined appropriate BMPs (which may include permeable pavement,oil/grease fiters, trash detention) that would reduce non-point source pollutants to levelsthat meet Regional Water Quality Control Board (RWQCB) limits.
Mitigation MeasureMeasure HYD-1 All development shall include measures consistent with therequirements and programs of the Deparment of Public Work to reduce contaminatedruoff in the adjacent body of water, including fitration of low flows, reduction of
impervious suraces, and provision of pump out facilities, and other necessary measuresto reduce harml pollutants. The Applicant shall prepare and submit a Storm Water
Pollution Prevention Plan (SWPPP) to the County for review and approval prior toproject constrction permt approval. The SWPPP shall identify the exact type of BestManagement Practices (BMPs), the timing and location of implementation, and thepurose and expected result of each BMP in protecting water quality and water flowcharacteristics. BMPs shall include measures to contain erosion and prevent theintroduction of toxic substances to ruoff. The SWPPP shall address pre-construction,constrction, and post constrction measures, and both temporary and permanent
measures. Recommended BMPs for the constrction phase include but are not limited tothe following:
. Proper stockpiling and disposal of demolition debris, concrete, and soil;
. Protecting existing storm drain inlets; stabilizing distubed areas;
. Erosion controls;
. Proper management of construction materials; and
. Waste management, aggressive litter control, and sediment controls.
These requirements shall be incorporated into design specifications and the constructioncontracts.
b) Less Than Signifcant Impact. The 1.5 acre improvement site is curently developedand mostly covered in impervious surfaces. The proposed project would have similar lotcoverage, and would include landscaped areas. However, the impervious surface of theproposed project may increase a small percentage due to the addition of the skateboardpark. The propert is not located in a groundwater recharge area or in an area considereda source of groundwater (URS, 2007). Groundwater was encountered at 34 feet below theground surface (bgs) at all borings durng subsurface investigation (URS, 2007). Basedon regional data, the historical highest groundwater level in the project vicinity is about10 to 20 feet below the existing ground surface (URS, 2007). The depth to groundwatermay fluctuate, depending on factors such as rainfall in the site vicinity. As a result,impacts would be less than significant.

c-d) Less than Significant Impact. The project site is curently developed and contains'established drainage patterns that would be maintained with the implementation of theproposed park redevelopment. The nearest flowing waterway is Dominguez Creek, whichis located adjacent to the EI Camo College and flows year-round between Alondra Park..and the college "In a southerly course toward the sea at San Pedro Harbor. The projectruoff would tie into existing stormdrains at the site, and would not substantially alter theexisting drainage pattern of a site through the alteration of the course of a stream or riveror, substantially increase the rate or amount of surace ruoff in a manner that wouldresult in flooding on- or off-site. Therefore, impacts would be less than significant.

Initial Study
The County Noise Ordinance establishes noise standards for .tlle project area. In addition,the Noise Element addresses noise with respect to general land use compatibility. TheCounty's Noise Element has adopted gudelines based on the community noise
compatibility criteria established by the State Deparment of Health Services CDHS) foruse in assessing the compatibilty of varous land use types with a range of noise levels.Other rating scales have been developed to account for the various effects of noise onpeople, which include the Equivalent Noise Level CLeq) and the Day Night Noise Level
CLdn). In addition, as the human ear is not equally sensitive to sound at all frequencies, aspecial frequency-dependent rating scale has been devised to relate noise to humansensitivity, or the A-weighted decibel scale CdBA).
The Los Angeles County General Plan Noise Element prohibits the development of newcommercial, industrial, or other noise generating land uses adjacent to existing residentialdwellngs if the operational noise from the new development exceeds 65 dBA CNELmeasured at the propert line of the residential land use. The Noise Element provides aninterior noise standard of 45 dBA CNEL for existing and proposed residential land use.Considering that typical residential strctures provide at least 20 to 25 dBA of exterior tointerior noise reduction, compliance with the County's noise criteria of 65 dBA wouldresult in noise levels within interior spaces that would be 45 dBA or lower. The NoiseElement also addresses the potential impacts associated with construction noise. TheNoise Element prohibits construction activities between the hours of 7:00 p.m and 7:00a.m.
As determined in the Response K.d) below, construction noise impacts to the closestsensitive land use would be less than significant with the implementation of nntigationmeasures. In addition, project operations would not result in a significant increase in noiselevels. As determined in Response K.c) below, noise due to long-term project operationswould be less than significant and no mitigations would be required. As such, theproposed project would not result in the exposure of persons to or generation of noiselevels in excess of standards established in the local general plan or noise ordinance, orapplicable standards of other agencies. Impacts would be less than significant.
b) Less Than Signifcant Impact. Vibration associated with noise, which taes the form ofoscilatory motion, can be described in terms of acceleration, velocity, and displacement.Typically, human response to vibration is not significant until the vibration exceeds 70 dB.Project construction would employ conventional activities and the equipment/techniquesto be used would not cause excessive ground-borne vibration. No pile driving or tunnelingwould occur. Project construction and operation would not generate significant levels ofground-borne vibration or ground-borne noise. For operations, the facility would continueto operate as a park and would not generate ground-borne vibration. Potential impactswould be less than significant.
c) Less Than Signifcant Impact. The proposed improvements would not result in a
permanent increase in ambient noise in the site vicinity above those occuring without theproject. Operation of the equipment proposed would not result in noise levels that exceed

applicable significance thresholds Ce.g. County's Noise Element or Muncipal Code).There would be no increase in ambient noise from project operation. Project operations arenot expected to exceed the County General Plan Noise Element compatibilty criterion of65 dBA CNEL for the propert line of sensitive land uses, and therefore would not resultin a significant impact "As a result, implementation of the proposed development wouldnot permanently increase ambient noise levels in the area and potential impacts would beless than significant
d) Less Than Signifcant Impact. The generation of noise associated with projectconstrction would occur on a temporar basis Ce.g. 20 months) for site preparation andconstruction activities. Constrction activities for the park improvements would result inless than one acre per day of distubed soiL. Constrction activities would create noise on ashort-term basis from heavy equipment and related construction activities. The operationof heavy equipment during constrction would result in temporary increases in noise in theimmediate vicinity of the constrction site. As shown on Table 2.4, average noise levelsassociated with the use of heavy equipment at constrction sites can range from about 78to 86 dBA, depending upon the types of equipment in operation at any given time and thephase of construction. The majority of the time, constrction noise levels at adjacentsensitive locations would be much lower, due to reduced constrction activity and thephasing of constrction Ci.e., constrction noise levels at a given location would be reducedas constrction activities conclude or move to another more distant location of the site).

Some land uses are considered more sensitive to noise than others due to the amount ofnoise exposure and the types of activities tyically involved. The nearest school sitesensitive receptor is the Evelyn Carr Elementary School, located at 6404 West 168th Streetor 0.6 mile south of the site (or approximately 3,800 feet). Other sensitive receptors
include the multifamily residences located across from the park on the other side of
Redondo Beach Boulevard. Current noise sources in the project area include typicalcommunity noise Ce.g., passenger vehicles, pets, and landscape maintenance operations).Construction noise impacts to the nearby residents would be avoided between the hours of7:00 p.m. to 7:00 a.m. as required by the County's noise element. Due to the short-termconstruction period, and the suffcient distance from the project site to the nearest school

Access to the improved parkwould be provided at the intersection of Redondo Beach Boulevard and Yukon Avenue.Construction activities would be short term (approximatelv 20 months) and wouldnot result in a substantial increase in traffc as compared to existin!! conditions. It isanticipated that approximately 1.000 truck trips wil be reauired to haul fillmaterials durin!! the four month !!radinwexcavation phase. The projeet does Bet R9:'/ea residential eompoffent and VlOlild Bot sigBifieanly increase traffc from a new SOllce.Durin!! operations. the proposed changes to the existing park would not substantiallyincrease traffic volumes beyond existing street capacity. The uses proposed are aredevelopment, modernization, and expansion of existing recreational uses on thepropert. Therefore, the proposed project would have less than a significant impact ontraffic conditions and road capacity.
b) Less Than Signifcant Impact. The proposed project is surounded by educational,commercial, and residential uses. The Alondra County Golf Course is located to the north

and west of the project site within the park, and EI Cannno College is located to thenortheast adjacent to park. Redondo Beach Boulevard rus diectly south of the site.Across Redondo Beach Boulevard are multi-fanly residences and an existingcommercial shopping center. The retail center includes small community serving vendorshops. The proposed project is a redevelopment of an existing park; it would not increasevisitors or employees and would not exceed the Level of Service (LOS) on designatedroads or highways. Therefore, the proposed project would have no adverse effect onnearby arterials.
c) Less Than Signifcant Impact. The proposed park redevelopment is located
approximately two and a half nnles south of the Hawthorne Municipal Airport. Theairport is located between West El Segudo Boulevard and 120th Street. The Compton!Woodley Airport is located approximately four miles east from the project site, locatedon the comer of Alondra Boulevard and South Central Avenue. The proposed project is aredevelopment of existing recreational propert and is not located within two nnles of anexisting public airport. The proposed recreational uses would not affect air traffc orflight patterns. Therefore, the proposed project would not pose a safety risk throughsubstantially increased air traffic levels.
d) Less Than Significant Impact. The proposed project is a redevelopment of existingrecreational facilities. The park is designed with convenient access to the proposedredevelopment at the intersection of Redondo Beach Boulevard and Yukon Avenue. Theproposed project is located in a residential and commercial community and would notpose hazards due to design featues. Therefore, the proposed project would have noadverse effects.
e) Less Than Signifcant Impact. The proposed project site would be serviced by the Los
Angeles County Fire Deparment. The Fire Departent curently has adequate access tothe project site off of Redondo Beach Boulevard. The proposed project would complywith all Building and Fire Code standards. The proposed project would have no adverseeffect on emergency access.
f) Less Than Significant Impact. The existing park contains adequate parking spaces for
the size of the facility. Construction personnel would be able to use the existing largeparking lot directly south of the project site. Parking for the redevelopment recreationaluses would remain the same. Access to the southern parking lot is provided off of theintersection of Redondo Beach Boulevard and Yukon Avenue. The proposed parkexpansion would retain all existing parking spaces. Alternate means of transporttion canbe used to access the park such as walking or biking. The proposed project is intended toserve nearby neighboring communities, many of which are within walking or bikingdistance of the site. The amount of parking spaces provided is deemed adequate based onthe location of the redeveloped recreational uses, the proxinnty of residences, and thefacility hours of operation.

facilities at the Alondra Community Regional Park. The proposed project would notsubstantially alter public services or utilities and is not expected to result in a significantphysical change in land use activities or major policy changes that would be detrimentalto long-term Regional Water Quality goals. Alondra Park curently contains facilities thatgenerate wastewater. The redevelopment of such facilities to improve appearance,effciency, and accessibility would not generate a negative impact. Therefore, proposedredevelopment of Alondra Park would not conflict with wastewater treatmentrequirements ofthe applicable Regional Water Quality Control Board.

b) Less Than Signifcant Impact. The proposed project's redevelopment would notsubstantially increase wastewater services. The park curently generates wastewater frompark patrons and maintenance; its renovation includes replacement restrooms and existingfacilties and the new facilties would generate similar amounts of wastewater. Please seeSection 16 Utilities response 16)a for further details. For these reasons, the proposedproject would result in less than a significant impact.
c) Less Than Signifcant Impact with Mitigation Incorporated. Please see the Hydrology
and Water Quality section for details and mitigation measures. The proposed projectwould have a less than significant impact with incorporated mitigation.
d) Less Than Signifcant Impact. Alondra Community Regional Park encompasses
approximately 84 acres; however, the project site improvement area is approximately 1.5acres. The Golden State Water Company (Central & West Basin Water Replenishment)currently services the park. The proposed project's redevelopment would include manyimproved and/or sinnlar uses that presently exist on-site. Collectively, the park isanticipated to use similar amount of resources. Therefore, the proposed redevelopmentarea of Alondra Community Regional Park is not anticipated to generate an adverseeffect to water supply resources.
e) Less Than Signifcant Impact. The proposed redevelopment of Alondra Community
Regional Park is not anticipated to have an adverse effect on its curent wastewatertreatment provider. Please see Utilties section, response "a" and response "b" for details.Therefore, the proposed project would have a less than a significant impact.
f) Less Than Signifcant Impact. During the demolition and constrction of the Alondra
Park's redevelopment, solid waste needs would be temporarily increased. However, uponcompletion of the park's improved recreational facilities, the amount of solid wastedisposal is anticipated to be similar to present demands. The completed redevelopment ofAlondra Park is not anticipated to substantially affect the above referenced utilities and isnot expected to result in a significant physical change in land use activities. Therefore,the proposed project would have less than a significant impact.
g) Less Than Significant Impact. The proposed project's redevelopment would comply
with federal, state, and local statutes pertaining to the regulation of solid waste. Pleasesee Utilities response "f' for fuer details. Therefore, the proposed project would have aless than significant impact.

b) Less Than Signifcant Impact with Mitigation Incorporated. The proposed projectwould not result in any cumulatively considerable impacts that would be potentiallysignificant or that would require mitigation. There are no impacts that would beindividually limited, but cumulatively considerable resulting from park improvements.There would be no change in land use designations as part of the project. The potentialimpact would be less than significant.
c) Less Than Significant Impact with Mitigation Incorporated. The proposed projectwould not result in a health hazard, and there would be no environmental effects thatwould adversely affect human beings, either directly or indirectly. The small quantity ofregulated materials potentially resulting from constrction activities (e.g. used oil,solvents, etc.) would be handled and disposed of in a manner that would comply with allregulatory requirements and potential health risks would be nnnimaL. During operation,

REpORT SUBJECT: Ficus tree evaluations
DATE OF SITE VISIT: May 31, 2007 & August 3, 2007
REpORT DATE: August 16, 2007
DEFINITION OF ASSIGNMENT
1. Discuss the growth habit of the Ficus species
2. Discuss the impact of root pruning on Ficus trees
3. Evaluate the health and condition of 13 Ficus trees on the south side of Alondra Park.
4. Discuss the impact of removing existing hardscape that surrounds the subject Ficus trees.
BACKGROUND
There are 13 matue Ficus microcarpa trees located at the entrance to the south side of Alondra Park.
The subject trees are a major component at the entrance to the park and figure prominently in the re-
designing of the park.
SITE OBSERVATIONS
. Subject trees are Ficus microcarpa in fair to good condition.
. All of the trees have received some level of pruning treatments in the recent past.
. The trees are surrounded by hardscape.
. Several trees are displacing the surrounding hardscape.
· Several of the trees are under moderate drought stress.

ANALYSIS & DISCUSSION
Growth habit of the Ficus species:
The subject trees are Ficus microcarpa, a fast growing, broad-headed, evergreen tree that can reach a
mature height of 60 feet or more with an equal spread of its canopy. With age they can develop amassive spreading dense
canopy that will cast'deepshade. They grow in fullsun or partial shade can
thrive II vanous well-
drained soils and are
moderately salt-tolerant.
Their canopies have glossy,
dark green, leathery leaves
. on large, somewhat weepingbranches. They produce
new growth all year longthat is a light rose to
chartreuse color, giving it an
attractive two-toned effect.
The trunks are smooth and light grey in color and can grow to three or four feet in diameter at the trunk
flare supported by an extensive surface root system. This species of Ficus does not produce aerial roots
which makes it a desirable street tree where ample room is available. They also make an excellent park
tree or shade tree on large properties with their broad canopy.
They tyically can go 4 - 6 years in between prune cycles depending on their location, can tolerateseveral different pruing treatments and can be cultivated into a hedge, screen or barrer. Regularpruning can also help to deter excessive fruit production which can stain cars and sidewalks and aregenerally messy on paved and other hard surfaces.
Ficus trees are quite resilient and can tolerate a high level of root pruning, provided they can remainstable. If root pruning is done improperly they will respond with massive amounts of root shoots which
eventually form a large woody mass that will displace most hardscapes. Their ability to endure rootpruning also makes them an ideal tree for relocating.

..¡"
Roots and the impacts of root pruing:
The surface roots perfonn the fuction of absorbing moisture and nutrients, are used for storing energyand provide structural support. Although tree roots in the Alondra Park area may grow as deep as 18
inches or more below the soil surface, the majority of the roots of the subject Ficus trees would probably
be found within the top 12" of the soil surface. When a tree's roots are severed, its àbility to absorbmoistue is reduced in addition to the lost energy reserves which were stored in the roots. Most of thetime root pruing causes irreparable damage from which the tree usually does not recover. When theroot pruing process involves stubbing off all of the roots in a specific area, the long tenn effects arehidden underground or within the root crown of the tree and do not reveal themselves until the exteriorsigns become apparent. During that time, a tree which has had its roots severed can still have a healthy
green looking canopy; however it does not necessarily mean the tree has recovered from having its roots
cut off and effects may not be discovered for several months to several years. It also does not mean the
tree is structually stable.
Oftentimes, the effects of root loss are difficult to associate with root pruning because of the time fromwhen the actual act of root pruning occurs and the discovery of the problems. Over time, thoseproblems are usually seen in the fonn of general tree decline, foliage loss, insect infestation, trunk
decay, or excessive production of epiconnic shoots (sometimes referred to as water sprouts) fonning along the
trnk or at the base of the tru. Extensive shoot growth at the tru and in some cases on the main
scaffold branches are indications that the tree has low energy reserves and the tree is in decline.
When the roots of healthy ficus trees are stubbed off from root pruing they usually respond with rootshoots in an attempt to replace the lost roots. In spite of this response the severed root branches begin to
decay as they cannot compartmentalize the wounds from the root pruing. That decay can eventually
spread into connecting roots and up into the trunk. At that time cracks begin to fonn at the trunk base
with strips of dead bark or cracks developing above the dead roots or perhaps between two dead roots.
In many cases, by the time these symptoms are discovered it is usually too late to remedy the situation
and management of the tree at that point consists of hazard evaluation, damage control or tree removaL.
Experience with the Ficus species has shown that although they have the capacity to tolerate theimmediate physiological effects of root pruning, strctural failure should never be ruled out. Ficus trees
that experience extensive and repeated root pruing over a period of several years may outwardly appear
to be healthy and stable, but have been known to fail during high winds, particularly after rainy weather,
or during extreme overnight cold temperatues regardless of wind conditions. A study of Ficus trees that
had failed under these conditions showed extensive decay at the base and center of their trunks with no
exterior evidence of decay.

Condition of the subject Ficus trees:
Most of the subject Ficus trees at Alondra Park are in good health, with some of them in moderate to
poor health due to lack of available moistue.
However, those that are in marginal condition also
have the potential to recover if they were to receive
regular moisture.
The tree shown in the photo at right is in goodhealth while the tree shown in the photo below is
experiencing drought stress. Typically when ficusare under drought stress they recover when they
find moistue.
Trees that are surrounded by hardscape such as
these trees have limited exposure to surface
moisture; moreover the concrete greatly reduces the
oxygen availability. This eventually contributes toroot decline which in tu has an adverse effect on
foliage production in the canopy. Although thiseffect can be seen on all of the ficus trees theproblem will most likely correct itself if they wereto receive regular moisture.

Although the tree shown in the photo below has asparse canopy it has good branch development and
a good root mass at its tru flare. This tree would
be a good candidate for relocation provided there is
ân effective post-relocation maintenance program
implemented that includes regular irgation untilestablishment.

.....
The tree shown in the photo below is also in marginal condition but appears to be recovering. Note the
new foliage on both sides, this is an indication the
roots may have found a source of moistue.
Overall the subject ficus are in good condition,
which obviously would improve once soilcondition and irrigation improvements can bemade. Given their heartiness and resilience theywill most likely thrive once they get regular
irrigation. Removing the concrete from around the
trunks will also increase the penneable surface
around the trees, allowing for more oxygen andmoistue. In tu this wil reinvigorate the trees.
The two trees that appear in the center of the photo
below are suffering from competition stress, where
they are competing for moistue and nutrients, butare slowly getting choked out by the neighboring
more aggressive trees. Nevertheless, they appear
to be in fair condition. This problem wil solveitself if all of trees in this stand were to receiveconsistent moistue thoughout the root zone.
In order to preserve as much of the surface roots as
possible, exceptional care should be taken when
removing the concrete. The concrete can be broken
up mechanically but should be removed manually
without disturbing the root mass underneath. Once
the concrete is removed the soil surface should be
raked clean of debris and covered with a light layer
of mulch. This wil help to prevent the surfaceroots that may become exposed to the air from drying out. The amendments in the mulch will alsoreinvigorate the soil with nutrients and trace elements crucial to the trees further growth.

" .All of the trees have good canopy strctue and have been well maintained throughout their lives in spite
of their curent drought stress. The main scaffold branches of several of the trees are tightly clustered at
the main stem. This has created a condition called included bark. Included bark is the bark that forms
as the codominant stems grow together, and remains between the individual stems. Codominant stems
are stems of about the same size that originated from the same position but are not held together by a
solid bond. Instead they are separate stems competing for space while they expand in girth. Over time
as they individually increase in girth, the weakest stem is eventually pushed away, causing its failure.
This has been known to happen with ficus that have not been pruned on a regular cycle and theircanopies become too heavy for limbs to support its own weight. Trees with this condition should bemonitored closely and where possible one of the stems could be removed in order to reduce the risk of
one of the stems failing.
The photos at right and below show an example of theincluded bark.

Tree protection during construction
When protecting trees in 'place during construction it is important to protect the area known as theCritical Root Zone (CRZ). That is an area ofundistubed natual soil around a tree. defined bytru' diameter in feet converted to twice the
number of inches of tru diameter. To accurately
detennine the critical root zone of a narrowcrowned tree, measure its tr diameter at 4.5 feet
above the ground with a diameter tape. Then
multiply that number by 1.5 and express the results
in feet. This same method can also be used to
detennine the size of box needed to successfully
relocate a tree.
Unless aggressive protection measures are established, the trees on site could be impacted by theconstrction on site. The movement of equipment and the storage of materials on a construction siteusually results in unwarranted soil compaction. Those negative impacts can be avoided byimplementing a tree protection zone (TPZ) around each individual tree or in the row of trees at the front
of the park. An example of how to indicate a TPZ on the plans is shown below.
Because soil compaction is extremely
difficult, expensive, and often impractical
to correct once it has occurred, the
emphasis is on prevention. While it maynot be practical to eliminate compactionfrom the entire constrction site, anumber of things can and should be done
to minimize its impact on trees.Vehicular traffc over the entire siteshould be kept to a minimum and routed
away from trees. Constrction work
should be perfonned with equipment
having good flotation and yet able toachieve the objective. Unnecessary traffc, such as workers' personal vehicles, should be prohibited on
the site. Movement over the site by delivery vehicles should be restricted as much as possible. A
storage area for construction materials should be identified that is well away from trees and located so as
to minimize the traffic required to retrieve and use the materials.

CONCLUSION
Overall the subj ect trees are II good enough shape to warrant their protection and preservation.Although the details of the design concept were not available at the time of site inspection the subject
ficus trees could conceivably be incorporated into the design, or relocated in order to accommodatethose future plans.

4.0 FIELD EXPLORATION PROGRA irj
â
~
,
1~¡ A field exploration program was initiated on Februar 2, 2007 and completed on same day
under the techncal supervision of a geotechnical engineer from our Los Angeles offce. The
subsurace conditions at the site w:ere explored by drllng and sampling thee borigs using atruck-mounted drllng rig, equipped with 8-inch diameter hollow-stem augers. The depthsofthe borings are approximately 51.5 feet. The locations ofthe borigs are shown on Figue
2.
t:f~.
.~
Both relatively undistubed ring-lined soil samples rrom a URS Type-U sapler andStadard Penetration Test (SPT) sampler (pr ASTM D 1586) were obtained by driving the
samplers 18 inches into the subsurace soils using a 140-pound hamer falling 30 inches.All blow counts were recorded at 6-inch intervals. The number of blows required to drvethe samplers the ffnal12 inches was recorded on the logs of borings. Bulk samples from thenea-surface soils were also collected rrom all borings. Upon completion of the drilingactivities, borings were backfilled with bentonite to the encountered water level and thencompleted with soil cuttings. .

6.0 GENERA SITE CONDITION
6.1 SURFACE CONDITIONS
The proposed project site is located withn Alondra Park to the north of Redondo BeachBoulevard and to the east of Yukon Avenue. From the parking lot fronting Redondo BeachBoulevard, the surounding ground descends approximately 3 feet though retaining wallsand stairs to the project site. The existig ground surface surounding project site is relativelyflat and is at an elevation of approximately 43 feet above mean sea level (MSL).
The proposed building and improvement locations are curently occupied by an abandonedswimming pool with a bottom elevation at approximately 36 feet MSL. The pool win bedemolished and backflled before the constrction of the new Pool HouselMulti-puroseBuilding and other improvements. Off the project limits, a playground is located to the westof the existing pool and a lake is located to the east of the pooL.
6.2 SUBSURACE CONDITIONS
The existing growwd surounding the project site at the locations explored is mantled by 0 to2 feet of arificial fill consisting ofloose, olive brown poorly graded sand. Underlyig thefill to final explored depth of 50 feet is alluvium consisting oflight brown to brown clay withvaryng minor amount of sand. The clay is generally with medium plasticity and increaes in
stiffess with depth from medium stiff at the ground surface to very stif generally below 20feet from the existing ground surace: Near the bottom of two of our borins (B-1 and B-3),sand and sandy silt layers were encountered.
6.3 GROUNDWATER
Groundwater was encountered at 34 feet below the ground surface (bgs) at all borings durg
our subsurface investigation. Based on regional data, the llstorical highest groundwater level
in the project viciiity is about 10 to 20 feet below the existing ground surace (CDMG,
i 998). The depth to groundwater may fluctuate, depending on factors such as rainfall in the
site vicinity.

7.0 GEOLOGICAL AND SEISMIC HAZARDS STUDY
7.1 GEOLOGIC SETTING
The site is located with the Los Angeles Basin which is situated at the jwwctue between the
Peiinsular Ranges Geomorphic Province and the Transverse Ranges Geomorphic Province.
The Los Angeles Basin is an elongate nortwest trending, sediment filled strctual trough
that began to take its present shape in the Late Miocene (about 7 milion years ago), bysubsidence between the right-oblique Whtter and Palos Verdes faults and the left oblique
Santa Monica fault system (Wright, 199 l).
1~
The site is at an elevation of about 43 feet above mean sea level, along the west sideDominguez Channel, approximately 3 miles west of the Rosecras Hils. The Californa
Division of Mines and Geology (CDMG), mapped Alondra Park as underlain by bothyowwger and older alluvium (CDMG, 1998). The project site at the southeast comer of
Alondra Park appears to be directly ilderlain by YOilger alluvium, which occurs along two
east flowing trbutares to Dominguez Chaael. The YOilger alluvium is described as a 10 to
20 foot thick valley deposit consistig of soft to ffnn clay, and clayey sands, that overlieolder alluvium. The older alluvium, which is at the surace away ftom these tributaiesgeneraly consists of stiff to hard clay and medium dense to very dense, sand, silty sand and
clayey sand.

7.2 FAULTING AN SEISMICITY
The project site is in a seismically active region that wil be subjected to futue seismic
shaking durg earhquakes generated by any of several suroilding active faults. TheNewport-Inglewood fault is the most signficant seismic source to the site. At its closest, the
Newport-Inglewood fault zone passes about 3 miles (5 km) to the norteast (CDMG, 1986).
The Newport-Inglewood fault was the source for the 1933 M6.3 Long Beach earhquake. It
caused major damage and the loss of 115 lives in Long Beach and surounding communties
of Los Angeles. The Newport-Inglewood fault is considered to connect with fault zones
south of Newport Beach (The "offshore zone of deformation", and the Rose Canyon fault)
forming a system of faults that extends from Santa Moiica to Baja California. It is

considered capable of generating an earquae as large as about magnitude 7 (CGS, 2003,
ICBO/CDMG, 1998).
7.3 GEOLOGICAL AND SEISMlC HAZARDS
7.3.1 Geological Hazards
Landslides
The proposed project site is in a relatively flat-lying area where landslides would not be
. expected to occur. In addition, the Seismic Hazards Zone maps for the Inglewood
Quadrangle indicate that the project elements do not lie with area designated as havig the
potential for earthquake-induced landsliding (CDMG, 1999).
Subsidence
The extrction of water or petrolewn ITom sedimenta rocks or deposits can cause thepennanent collapse of the pore space previously occupied by the removed fluid. The
compaction of subsurace sediment caused by fluid withdrawal will cause subsidence of the
ground surface overlying a pumped reservoir. If the volume of water or petroleum removed issuffciently great, the amount of resulting subsidence may be suffcient to damage nearby
engineered structues. The project site is situated well outside any oil field and the area is not
known to be in an area with signficat ground water pumping. Although a detaled study has
not been performed for ths report, it is anticipated that the curent minor amount of water
extraction from water wells in the vicinity of the site wOlÙd not result in meaurablesubsidence at the project site. Therefore, the potential for subsidence is not considered a
signcant geologic hazard to the project
7.3.2 Seismic Hazards
Primary Ground RupturePrimary ground ruptue is ground deformation that occurs along the surace trace of the
causative fault durig an earquake. No known active or potentially active fault traces have
been recognized as crossing any par of the proposed project and Californa Geological
Surey (CGS) does not delineate any par of the project area as being within an Alquist-
Priolo Earthquake Fault Zone (CDMG 1986,1997).
Because there are no active or potentially active faults known to be present crossing theproject site, the potential for surface fault ruptue is considered unikely.

Strong Ground Motion
Strong ground motion occurs as energy is released durng an earhquake. The intensity ofground motion is dependent upon the distance between the site and the eahquake, the .magnitude of the earhquake, and the geologic conditions underlying and surounding the
site. Earhquakes occurng on faults closest to the site would most likely generate the largest
ground motions.
As is the case with most of southern California, the site is located within an area subject to
relatively strong ground motions. Proposed strctues should be designed with seismic
paaameters presented in Section 8.6 of this report.
Liquefaction
Liquefaction is a phenomenon where satuated coarse-grained soils (less than 50% passing
the No 200 sieve) lose their strengt and acquire some mobilty from strong ground motion.
A rapid increase in groundwater pressures (excess porewater pressures) causes a loss of shea
strength. The primar secondar effects of liquefaction include sand boils, settlement and
settlement-related downdrag on deepened foundation systems, lateral spreading and flow
slides in areas with sloping ground. Liquefaction tyically occurs in soils such as sands, silty
sands and to lesser extent clayey sands that are loose and located below groundwater.
However, liquefaction usually does not manifest at the surface when it occurs at depths
greater than 50 to 60 feet due to the larger overburden pressures.
The Californa Geological Survey has designated certain areas withn Californa as potential
liquefaction hazard zones. These are areas considered at greater risk ofliquefaction-related
ground failure duung a seismic event, based upon mapped surcial deposits and the presenceof a relatively shallow groundwater table. Based on the Seismic Hazard Map for the
. Inglewood Quadrangle (COMG, 1999), the project site is not located withn a Liquefaction
Hazard Zone. Furher more, subsurace investigation indicates that the site is underlain by
mostly stiff clay soil that is not poise to liquefaction. Therefore, liquefaction potential at the
project site is considered to be low.

Seismically Induced Landslides
As noted above, the project lies in a relatively flat-lying area where landslides would not be
expected to occur. fu addition, the Seismic Hazds Zone Map for the fuglewood
Quadrangle, indicates that the project elements do not lie within areas designated as havingthe potential for earhquake-induced landsliding (CDMG, 1999). Therefore, the potential for
landslides induced by seismic shakg is not anticipated to pose a signcant seismic hazad
to the proposed project
Earthquake Induced Flooding
Earhquake induced flooding occurs when nearby water retaing strctues, such as das or
storage tank, are breached or damaged durng an earquake. The site is not curentlylocated within a flood or inundation hazd zone according to the Los Angeles County SafetyElement (1990). Based on this information, there appears to be minimal risk of earhquakeinduced flooding with the vicinity of the site ¡1

Other seismic floodig hazards include tsunamis and seiches. These hads do not exist at

8.0 DISCUSSIONS AND RECOMMENDATIONS
8.1 GENERAL
.¡
l ¡
¡
Based on the results of our geotechnical investigation and our understading of the projectrequirements, the site can be developed for its intended purose provided therecommendations in this report are incorporated in the design and implemented duringearwork and construction of the project.
With respect to geological and seismic hazds, no faults are known to exist within theproject sites; accordingly, the possibility of surface ruptue of the site due to faulting isremote. Although the site could be subject to signficant ground shaking in the event of amajor earquake, this hazd is common to southern Californa and possible damage caused
by the shakng can be reduced by proper strctual design and constrction.
,.,,1'.
~
The proposed Pool HouselMulti-purose Buiding and the relatively lightly-loadedimprovements can be supported on conventional spread footings. The building pad for theproposed Pool HouselMulti-purose Building and improvements wil be created afterabandoning and backflling the existing swimmng pool, which is about 7 feet deep.Although the clayey alluvial deposits have a potential for volumetrc chane and pressue
increase with variations in moistue content, we anticipate that the shallow foundations of thePool HouselMulti-purpose Building and improvements wil be founded into engineeredimport fill, whose expansive charactenstics can be conditioned and controlled.
,.
,,
At the preparation of this report there are no details about the method of the existingswimming pool abandonment. It will be preferable for the pool shell to be removed entirely
before the placement of backflls. However, if the pool shells are to be abandoned in placebecause of cost, the upper 5 feet of pool shells interfenng with foundations should beremoved and holes should be driled into the pool shells to be abandoned in place to faciltate
drainage.

We expect a signficant amount of import fill win be needed for the project and the borrowsource is unown at the preparation of this report. Our recommendations presented hereinare based on past project expenence with engineered fills and additional laboratory testing
will be necessar during constrction to venfy the asswned values. These tests wil likelyinclude, but not limited to, direct shea, consolidation, expansion potential, compaction and
corrosivity.

8.2 EARTHWORK
8.2.1 Site Preparation
Pdor to the star of site grading, some of the existing structures, including the abandoned
swiming pool, will be demolished to faciltate new constrction. Any debris, organicmaterials and deleterious materials should be removed and disposed of outside theconstrction limits under observation by the Geotechnical Engineer of Record. All
foundation elements, if any, should be removed. All active or inactive utilties withn the
construction limits should be identified for relocation, abandonment, or protection prior to
grading. Any pipelines greater than 2 inches in diameter to be abandoned in-place should befilled with sand/cement slur after review oftheir location and approval of the GeotechncalEngineer of Record.
-,r
;i
The upper 8 inches of native subgrade with proposed improvement areas for futue support ofstrctu loads, or engineered fill should be scarfied and proof-rolled with a rubber-tie loader
or other heavy equipment to remove any soft or loose zones. In-place compaction may be
diffcult if the soft or loose zones are greater than about 12 inches in thckness, and removal and
recompaction in separate lifts may be necessar.
¡:.
-~
8.2.2 Fils and BackfIJs
8.2.2.1 General
We anticipate that a signficant amount of fill materials will have to be imported to backfllthe existing swimming pool to create the building pad. The minor amount of materials to be
generated from excavations wil be consisting of clayey alluvial deposits. Based on theclayey nature of the on-site material, a medium to high expansive potential should beasswned. If the clayey excavated soils were to be re-used in compacted fill, thorough mixing
with coarse grain fill materials would be necessar. The resulted mix should have amaximum of35% of fines passing a stadard No. 200 sieve and an expansion index (EI) not
exceeding 30. The mix should be confrmed and approved by the Geotechncal Engineer ofRecord for their suitabilty before placing.
.f
j',,,;:"
.. 8.2.2.2 Import Materials Criteria
No soil should be imported to the site without the prior approval by the Geotechncal
Engineer of Record. If import soil is considered for this project, the new fill should be
predonnnantly granular in natue, with an Expansion Index ofless than 20. For gradation, the

new fill should contain no rocks in excess of3 inches in maximum dimension, and no more
than 20% of fines passing a standard No. 200 sieve. In addition, aggregate base and trench
bedding materials should confonn to the Green Book or similar standards. All new fills
should be free of hazdous, organc and inorganic debris. All fill and backfll materials
should be observed and tested by the Geotechrcal Engineer of Record in order to detennetheir suitability.
8.2.2.3 Compaction Criteria
Fils and backflls should be placed in loose lifts not exceeding 8 inches in thickness, and
moisture conditioned as required to achieve near-optimum moiste content No compaction
by ponding or jetting should be allowed. All fills in the proposed building area should be
compacted to 95 percent, while other fills and backflls should be compacted to 90 percent of
their maximum dry densities. If specified relative compaction is not achieved, additional
compaction effort, moistue conditioning of the fill soils, and/or removal and recompaction
of the below-minimum-compacton soils will be required at the expense of the contractor..
l

t"
No fill should be placed, spread or rolled during unavorable weather. When the work is
interrpted by rain, operations should not be resumed until field tests by the Geotechncal
Engineer of Record have indicated that conditions will pennit satisfactory results.

8.2.3 Temporary Excavation
.~
Excavation and safety during constrction is the sole responsibilty of the Contrctor who
should perfonn an independent assessment of the proposed excavation. Excavations should
be perfonned in accordance with applicale local, state, and federal regulations and safety
ordinances such that excessive ground movement and failure will not occur.
1
1:
~¡~
It is anticipated that shallow temporar excavations will be required for the foundations.
Unsupported and non-surcharged temporar excavations can be made up to 5 feet deep. For
deeper cuts up to a maximum of20 feet, temporar excavations can be made at a gradient no
steeper than 1: i (horizontal to vertical, H: V). Construction slopes excavated in accordance
with the above criteria are considered to have a factor of safety in excess of 1.25 under
temporar static loading conditions. In areas where soils with little or no binder areencountered, shorig or flatter excavation slopes may be necessar.

It is expected that excavation for the proposed consruction can generally be accomplÍshedusing conventional earoving equipment. The top of excavations should be graded to
prevent ruoff from entering the excavation, wetting the soils, and eroding the excavatedfaces. Surcharge loads from vehicle parking and traffc or stockpile materials should be setback from the top of temporar excavation a horizontal distance equal to at least the depth of
excavation. Even with the implementation of these recommendations, sloughing of thesurace of temporar excavations may stil occur, and workers should be adequately
protected.
8.3 FOUNDATION DESIGN
8.3.1 Allowable Bearing Capacity
~
J~
An allowable beaag pressue of2,500 pounds per square foot (pst) may be used for shallow
footings with a minium width of 2 feet and a minimum embedment depth of 24 inchesbelow the lowest adjacent grde for perimeter footings, or top of slab for interior footing,bearing into engineered fill. The depth offill should be no less than 3 feet below the bottomof any footings and the limits of fill should extend at least 5 feet beyond the edges of allfootings, or equal to the depth of fill below the foundations, whichever is greater. Therecommended bearing pressure can be increased by 20 percent with each additional foot ofdepth to a maximum value of3,500 psf.
The above allowable beang pressures are net values, and the weight of the foundation andbackfll over the foundation to the sub grade level may be neglected when computig deadloads. The bearig pressure applies to dead plus live loads and includes a calculated factor of
safety of at Least 3. The allowable bearing pressure values may be increased by one-ttrd for
short-tenn loading due to wind or seismic forces.~
~.~

8.3.2 Settlement
f,
Total static settlements of individual foundations wil var depending on the width of thef01ldation and the actual load supported. Based on the recommended bearing pressure, the
tota settlements of shallow footings designed and constructed in accordance with the
preceding recommendations are anticipated to be less than 1 inch. Differential settlements
between similarly loaded adjacent footings may be assumed to be half of the total settlement.

application of the design loads. As a precaution) strctual and utility connections to newconsruction supported on shallow foundations should be deferred until after the majority of
the dead loads have been applied.
8.3.3 Lateral Resistance
Resistance to lateral loads may be provided by ftictional resistance between the bottom ofconcrete footings and the underlying soils and by passive soil pressure against the sides of thefootings. The allowable coeffcient of frction betwen poured-in-place concrete footigs andthe underlying engineered fill may be taken as 0.4. Allowable passive pressure available inengineered fill may be taen as 350 pound per cubic foot (pet) to a maximum value of3,500
psf. The above-recommended values include a factor of safety of at leat 1.5. Friction andpassive resistance may be used in combination, if the passive resistance is reduced by one-
half.
8.4 LATERAL EARTH PRESSURES
,¡-,
'I
~
Pool shells and retaining walls, if there are any, should be designed to resist lateral ear
pressure.

~
~~
Static earth pressure on walls retaning level granular backfill can be calculated as an .equivalent fluid pressure of 3 5 pcE The recommended design lateral earh pressure assumesthe walls will be properly back-drained. One acceptable method for back-drning the wall is
to place a prefabricated drainage panel against the backside of the wall with a collector pipe
at the base of the drainage paneL. The collector pipe should be a four-inch perrorated pipeplaced with its holes down and surounded by at least 12 inches of% inch gravel, which areenveloped in a drainage fabric, such as Miraf 140N or equivalent The drinage panel should
extend at leat six inches below the finish grade behind the retaining walls.

A moisture barer is recommended under all floor slabs to be overlain by moistue-sensitivefloor covering. A plastic or vinyl membrane may be used for this purose and should beplaced between two layers of moist sand, each at least 2 inches thick, to promote uniformcuring of the concrete and to protect the membrane during constrction.
Hardscape and decking should be at least 4 inches thick and they should be reinforced with#3 reinforcement bars spaced a maximum of24 inches each way. The hardscape and decking
should be underlain by a minium of2 inches of sand to aid in concrete curing.
8.6 SEISMIC SITE COEFFICINTS
In order to estimate the level of shakg that can be expected at the site, a detennnistic
evaluation according to the 2001 Californa Building Code (CBC) wa conducted. According
to the CBC all components of the project are located withi Zone 4. The Newport-Inglewood
fault, which is estimated to be capable of generating a maximum magnitude 6.9 earquake,
is located about 3.8 mies (6 km) from the project site and will govern the seismic design at
the project site. The Newport-Inglewood fault is classified as a Type B fault (International
Conference of Building Offcials, i 998). The subsurace materials likely correspond to Soil
Type "SD" for the purose of ground motion evaluation. Based on these inputs, thecorresponding seismic design parameters from the 2001 CBC are as presented in the
following table.

Based on Table 19 A -4 of the 2001 CBC, the sulfate concentration detected is at a negligible
leveL. As a result, no special precaution would be required for cement to be used at the
subject site in direct contact with any native soiL. Minimum strength and workmankeconcrete constrction practices wil be suffcient to protect against this low sulfateconcentration encountered.

The chloride test indicates that the cWoride content present at the on-site native soil is at a
negligible concentrtion. Consequently, no consideration of additional concrete cover would
be necessar for the reinforcing steel.
It should be noted that soil COITosivity should be tested during construction to verify the
design recommendation.

9.0 DESIGN REVIEW
The geotechnica aspects ofthe project should be reviewed by the Geotechnical Engineer of
Record durng the design process. The scope of services may include assistance to the design
team in providing specific recommendations for special cases, reviewing the foundationdesign and evaluating the overall applicabilty of the recommendations presented in thisreport, reviewing the geotechnical portions of the project for possible cost savings throughalternative approaches and reviewig the proposed constrction technques to evaluate if theysatisfY the intent of the recommendations presented in this report.
10.0 COUNTY BUILDING CODE SECTION 111 STATEMENT
~..~
t
Based on the findings of this geotechhcal investigation, and provided that therecommendations ofthis report are followed, and the designs, grading and slope repairs are
properly and adequately executed, it is our opinon that the slope mitigation/repair workwithin the referenced site would not be subjected to geotechncal and geologic hazds from
landslides, slippage, or settlement. Furer, it is our opinion that the proposed slope repairsand anticipated site grading would not adversely afect the stability of the site, or adjacentproperties, with the same provisos listed above.

Mitigation Monitoring and Reporting Program
The County of Los Angeles Department of Public Works (LACDPW) has proposed toupgrade the existing facilities located at Alondra Community Regional Park in LosAngeles County, CA. The park encompasses approximately 84 acres of land andincludes a children's play area, an urban lake, gymnasium, lighted baseball/softballfields, multipurpose room with kitchen, picnic areas with barbeque braziers, a swimmingpool (currently unused), and a volleyball court. The improvements would be located tothe north of the existing parking lot on approximately 1.5 acres and would includeredevelopment of the existing swimming pool and picnic area and construction of a newpool house, water play area, recreational offce, and skateboard park. The proposedproject would meet the requirements of the Americans with Disabilities Act (ADA).
Section 21081.6 of the California Public Resources Code requires a Lead Agency toadopt a reporting or monitoring program for the changes made to the project orconditions of project approval, adopted in order to mitigate or avoid significant effects onthe environment. CEQA Guidelines Section 15097 summarizes the criteria required formitigation monitoring and/or reporting. This Mitigation Monitoring and Reporting Program
(MMRP) is designed to monitor implementation of the mitigation measures identified forthe project, and meets applicable statues to avoid or to mitigate identified potentialimpacts to a level where no significant impact on the environment would occur. TheCounty will have the responsibility for implementing the measures, and various publicagencies wil have the primary responsibility for enforcing, monitoring, and reporting theimplementation of the mitigation measures. The required mitigation measures are listedand categorized by impact area, with an accompanying identification of the following:
. Mitigation Measure
. Mitigation Procedure
. Responsible Party (agency or party with the power to enforce the mitigation
measure)
. Mitigation Timing (the phase of the project during which the mitigation
measure shall be implemented and monitored):
- Pre-Construction, including the design phase
- Construction
- Occupancy (post-construction monitoring is not required)
. Monitoring and Reporting Procedure
. Verification of Compliance (for use during the reporting/monitoring)
This MMRP is a compliance verification report, with space for confirming mitigationmeasures have been implemented for the project.

Dear Mr. O'Brien:
The Department of Toxic $ubstances Control (DTSC) has received the InitialStudy/Mitigated Negative Declaration for the subject project. The Los Angeles CountyDepartment of Public Works proposes to upgrades to facilities within the Alondra .Community Regional Park. The project includes the demolition, redevelopment andimprovement of some of the existing facilties within the Park; the redevelopment andimprovement areas are located to the north of the parking lot. A minor amount ofgrading is proposed in the building pad areas and to provide proper drainage. Based onthe review of the document, DTSC comments are as follows:
1. Soil contamination could be present on the propert from formerpesticide/herbicide use for landscaping and pesticide use for rodent control, fromchemical pool supply spils, or from possible ilegal dumping on the propert;historicai dumping of debris, bum material, or contaminated material in formerdrainage swales and gullies could have occurred on site prior to the Parkdevelopment. Contaminated groundwater may be present beneath the proposedredevelopment areas that migrated from upgradient industrial sites. Hazardous .materials contained in storm water run-on to the park from adjacent streets mayhave also contaminated groundwater beneath the site.
2. Proper investigation and remedial actions should be conducted at the Site priorto its development. All environmental investigation and/or remediation should beconducted under a workplan which is approved by a regulatory agency who hasjurisdiction to oversee hazardous waste cleanups.
3. If during construction of the project, soil contamination is suspected, constructionin the area should stop, and appropriate health and safety procedures should beimplemented. If it is determined that contaminated soils exist, the draft EIR

LETTER A - CALIFORNIA DEPARTMENT OF TOXICSUBSTANCE CONTROL (DTSC) (October 31,2007)
A-1 The DTSC suggests that project construction may require soil excavation andsoil filling in certain areas and appropriate sampling is required prior to disposalof the excavated soiL.
Response: As discussed in the Hazardous Waste section of the IS/MND, item G(d), areview of federal and state environmental databases revealed no environmental
concerns or issues related to hazardous waste or materials occur for the project site.The proposed property is not listed as a hazardous materials site; therefore, nocontaminated soils are expected to occur. In addition, the site is primarily flat with theexception of a topographical depression that traverses the site and only fine gradingwould be required. Excavation of soils in a manner resulting in disposal is not anticipatedto occur. In the event of discovery of contaminated soils during project construction oroperation, compliance with all applicable regulations pertaining to handling and disposalof such materials will be implemented.
A-2 DTSC requires investigation and appropriate remedial action be conducted priorto site development. In addition, DTSC requires that a work plan be developedand approved by a regulatory agency who has jurisdiction to oversee hazardouswaste clean-ups.
Response: See response A-1 above. There are no known issues pertaining tohazardous waste or related contamination, therefore a workplan will not be required forproject renovations.
A-3 DTSC requires that, if contamination is discovered during construction, suchactivities stop and appropriate health and safety procedures be implemented.
Response: Comment noted. Appropriate actions will be implemented in the eventcontamination is discovered during construction and operation of the project.
